binfmt_misc: use __free(kfree) in bm_register_write()

bm_register_write() has to free the entry it got from create_entry()
on every failure until add_entry() has linked it into the filesystem
and made the inode its owner. Arm the entry with __free(kfree) so the
error branches can simply return and disarm it via
retain_and_null_ptr() once ownership has been handed to the inode.
The interpreter file keeps its manual error cleanup as freeing the
entry would not close it.

No functional change.
