Subject: mmap locking API: fix missed mmap_sem references in comments
Git-commit: 5b4494896cb379b0304ba8320589f2ffd08a7b31
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Commit c1e8d7c6a7a6 ("mmap locking API: convert mmap_sem comments") missed
replacing some references of mmap_sem by mmap_lock due to misspelling
(mm_sem instead of mmap_sem).
