Fix deadlock while invalidating VFS dentry

Ie0ea946245fe67e8ad93e3da4f59d6b87d103331 introduced a regression
where we hold the fuse lock while invalidating a FUSE dentry. The
documentation for fuse_lowlevel_notify_inval_entry says to *not* call
'inval' in the execution path of a related fuse op or hold a lock
that could be needed in the execution path of a related FUSE op.
