LU-6137 ldiskfs: simplify nocmtime patch
Simplify the nocmtime patch by patching only ext4_current_time(),
this fixed the defect that original patch doesn't handle setacl
code path, it can also avoid the risk of future changes adding
new places that needs to be fixed.
Remove the obsolete xattr-no-update-ctime patch.
