xen/blktap: fix cleanup after unclean application exit

When an application using blktap devices doesn't close the file handle
(or mmap-s) of /dev/xen/blktapN, we cannot defer the mmput() on the
stored mm until blktap_release(), as that will never be called without
the mm's reference count dropping to zero.
