The s_subtype field is initialized after calling vfs_kern_mount(), so we can't
check s_subtype inside vfs_kern_mount(). Instead of s_subtype we can check
dev_name, but this leads to an unjustified modification of common fuse.
Given that s_subtype/dev_name check doesn't protect from the possibility to
mount fuse whith kpcs on any device except vstorage/pstorage, we can remove
this check.
