drm/i915: Report -EFAULT before pwrite fast path into shmemfs
When pwriting into shmemfs, the fast path pagecache_write does not
notice when it is writing to beyond the end of the truncated shmemfs
inode. Report -EFAULT directly when we try to use pwrite into the
!I915_MADV_WILLNEED object.
Fixes: 7c55e2c5772d ("drm/i915: Use pagecache write to prepopulate shmemfs
from pwrite-ioctl")</pre>
