xfs: rename variable mp to parsing_mp

mainline inclusion
from stable-v5.13-rc1
commit 0f98b4ec
category: bugfix
bugzilla: 186908, https://gitee.com/openeuler/kernel/issues/I4KIAO

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0f98b4ece18da9d8287bb4cc4e8f78b8760ea0d0

--------------------------------

Rename mp variable to parsisng_mp so it is easy to distinguish
between current mount point handle and handle for mount point
which mount options are being parsed.
