VME: Provide access to VME bus enumeration and fix vme_user match function
The match function for vme_user is completely wrong. It will blindly bind
against the first VME slot on each bus (at this point that would be just the
first bus as the driver can only handle one bus).
The original intention (before some major subsystem changes) was that the
driver bind against the slot to which the bridge was attached in the VME
system and to the bus(es) provided via the "bus" module parameter.
To do this cleanly (i.e. without poking arround in the subsystems internal
stuctures) a functionality has been added to provide access to the bus
enumeration.

An irq is only needed by this driver in order to support async commands.
Since it is optional, modify the attach so that if the request_irq() fails
the attach does not fail.
Remove the printk noise about the irq.
Only hookup the async command support if the request_irq() was successful.
Also, only call dt282x_grab_dma() if we have an irq since interrupt support
is needed to support dma.

When a system runs out of memory and the function
ptlrpc_register_bulk() is called from ptl_send_rpc() the call to
LNetMEAttach() fails due to failure to allocate memory. This forces
the code into an error path, which most probably previously went
untested. The error path:
if (rc != 0) {
CERROR("%s: LNetMEAttach failed x"LPU64"/%d: rc = %dn",
desc->bd_export->exp_obd->obd_name, xid,
posted_md, rc);

This print assumes that desc->bd_export is not NULL. However, it is.
In fact it is expected to be NULL. desc->bd_import is the correct
structure to access in this case.

ll_lookup_it() checks for O_CREAT in struct lookup_intent's

for IT_CREATE in it_op. This will not affect the behavior of either
function, since if O_CREATE (0100) is actually set in o_create_mode
then IT_CREATE must have been set in it_op. In ll_atomic_open() check
for O_CREAT in the open_flags parameter rather than testing mode.
