[PATCH 01/15 v2] UBIFS: improve function-level documentation

[PATCH 01/15 v2] UBIFS: improve function-level documentation

[Julia Lawall]

Fix various inconsistencies in the documentation associated with various
functions.

In the case of fs/ubifs/lprops.c, the second parameter of
ubifs_get_lp_stats was renamed from st to lst in commit 84abf972ccff
("UBIFS: add re-mount debugging checks")

In the case of fs/ubifs/lpt_commit.c, the excess variables have never
existed in the associated functions since the code was introduced into the
kernel.

The others appear to be straightforward typos.
