gfs2: Rename gfs2_withdrawn to gfs2_withdrawing_or_withdrawn

Browse Source 
[ Upstream commit 4d927b03a6 ]

This function checks whether the filesystem has been been marked to be
withdrawn eventually or has been withdrawn already.  Rename this
function to avoid confusing code like checking for gfs2_withdrawing()
when gfs2_withdrawn() has already returned true.
