In theory the problem here is that if size is in the 1-3 range then we
don't allocate enough memory for the posix_acl_xattr_header struct and
it results in memory corruption. But in reality kmalloc() return values
are aligned at sizeof(long) so corrupting this small amount of data is
not harmful.
The "size" variable should be type size_t. The value of size is checked
in setxattr() so we know it is a number between "0 - XATTR_SIZE_MAX".
There is no need to check for negative sizes.

staging: comedi: comedi_test: fix timer lock-up
Commit 240512474424 ("staging: comedi: comedi_test: use
comedi_handle_events()") resulted in the timer routine
`waveform_ai_interrupt()` calling `comedi_handle_events()` instead of
`comedi_events()`. That had the advantage of automatically stopping the
acquisition on overflow/error/end-of-acquisition conditions (by calling
the comedi subdevice's "cancel" handler), but currently results in the
timer routine locking when one of those conditions occur. This is
because the "cancel" handler `waveform_ai_cancel()` calls
`del_timer_sync()`.
Fix it by adding a bit to the device private data that indicates whether
the acquisition is active or not, and changing the "cancel" handler to
use `del_timer()` instead of `del_timer_sync()`. The bit is set when
starting the acquisition, cleared when ending the acquisition (in the
"cancel" handler), and tested in the timer routine, which will do
nothing if the acquisition is inactive. Also, make sure any scheduled
timeout event gets cancelled when the low-level device gets "detached"
from the comedi core by calling `del_timer_sync()` in the "detach"
handler `waveform_detach()`.
