    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")
