Andriy Gapon f4043145f2 ZFS vn_rele_async: catch up with the use of refcount(9) for the vnode use count 
It's not sufficient nor required to use the vnode interlock when
checking if we are going to drop the last use count as the code in
vputx() uses refcount (atomic) operations for both checking and
decrementing the use code.  Apply the same method to vn_rele_async().
While here, remove vn_rele_inactive(), a wrapper around vrele() that
didn't add any value.

Also, the change required making vfs_refcount_release_if_not_last()
public.  I've made vfs_refcount_acquire_if_not_zero() public as well.
They are in sys/refcount.h now.  While making the move I've dropped the
vfs_ prefix.
