[for-6.13 PATCH 15/19] nfs_common: rename nfslocalio nfs_uuid_lock to nfs_uuids_lock

[Mike Snitzer <snitzer@kernel.org>]

This global spinlock protects all nfs_uuid_t relative to the global
nfs_uuids list.  A later commit will split this global spinlock so
prepare by renaming this lock to reflect its intended narrow scope.
