hostmem: no need to check for host_memory_backend_mr_inited() in alloc()

Browse Source 
memfd_backend_memory_alloc/file_backend_memory_alloc both needlessly
are are calling host_memory_backend_mr_inited() which creates an
illusion that alloc could be called multiple times but it isn't, it's
called once from UserCreatable complete().
