drm/vmwgfx: Don't use memory accounting for kernel-side fence objects
Kernel side fence objects are used when unbinding resources and may thus be
created as part of a memory reclaim operation. This might trigger recursive
memory reclaims and result in the kernel running out of stack space.
So a simple way out is to avoid accounting of these fence objects.
In principle this is OK since while user-space can trigger the creation of
such objects, it can't really hold on to them. However, their lifetime is
quite long, so some form of accounting should perhaps be implemented in the
future.
Fixes kernel crashes when running, for example viewperf11 ensight-04 test 3
with low system memory settings.

drm/vmwgfx: Fix error printout on signals pending
The function vmw_master_check() might return -ERESTARTSYS if there is a
signal pending, indicating that the IOCTL should be rerun, potentially from
user-space. At that point we shouldn't print out an error message since that
is not an error condition. In short, avoid bloating the kernel log when a
process refuses to die on SIGTERM.

The DRM connector's encoder pointer is managed internally by the DRM
core and set to NULL when the DRM connector is disconnected from the
CRTC it was attached to. This results in a NULL pointer dereference in
the HDMI connector functions when trying to call the associated slave
encoder's operations.
Fix this by retrieving the slave encoder pointer from the R-Car
connector structure instead of the DRM connector structure.

with explicit get_pages for the context object as there may be no backing store
