vfs: Remove duplicated d_mountpoint check in __is_local_mountpoint
This function acts as an out-of-line helper for is_local_mountpoint
is only called after the latter verifies the dentry is not a mountpoint.
There's no semantic changes and the resulting object code is smaller:
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-26 (-26)
Function old new delta
__is_local_mountpoint 147 121 -26
Total: Before=34161, After=34135, chg -0.08%
