filelock: fix name of file_lease slab cache

Browse Source 
[ Upstream commit 3f65f3c099 ]

When struct file_lease was split out from struct file_lock, the name of
the file_lock slab cache was copied to the new slab cache for
file_lease. This name conflict causes confusion in /proc/slabinfo and
/sys/kernel/slab. In particular, it caused failures in drgn's test case
for slab cache merging.
