kill-the-bkl/reiserfs: always lock the ioctl path

Browse source

Reiserfs uses the ioctl callback for its file operations, which means
that its ioctl path is still locked by the bkl, this was synchronizing
with the rest of the filsystem operations. We have changed that by
locking it with the new reiserfs lock but we do that only from the
compat_ioctl callback.

Fix that by locking reiserfs_ioctl() everytime.
