gfs_file_inactive: replace bad code with ugly code

Also, make it explicit that V_XATTRDIR is not properly supported in gfs
code yet.

The bad code was plain incorrect: (a) it spoiled handling of v_usecount
reaching zero and (b) it leaked v_holdcnt.

The ugly code employs potentially unsafe locking tricks.

Ideally we should separate vnode lifecycle and gfs node lifecycle.
A gfs node should have its own reference count where its child nodes
should be accounted.
