xfs: Use xfs set and clear mp state helpers

Use the set and clear mp state helpers instead of open-coding.

It is noted that in some instances calls to atomic operation set_bit() and
clear_bit() are being replaced with test_and_set_bit() and
test_and_clear_bit(), respectively, as there is no specific helpers for
set_bit() and clear_bit() only. However should be ok, as we are just
ignoring the returned value from those "test" variants.
