[PATCH -next] binderfs: fix error return code in binderfs_fill_super()

[Wei Yongjun <weiyongjun1@xxxxxxxxxx>]

Fix to return a negative error code -ENOMEM from the new_inode() and
d_make_root() error handling cases instead of 0, as done elsewhere in
this function.

Fixes: 3ad20fe393b3 ("binder: implement binderfs")
