compat_ioctl: block: handle Persistent Reservations
These were added to blkdev_ioctl() in linux-5.5 but not
blkdev_compat_ioctl, so add them now.
Cc: <stable@vger.kernel.org> # v4.4+
Fixes: bbd3e064362e ("block: add an API for Persistent Reservations")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Fold in followup patch from Arnd with missing pr.h header include.
