fs/super.c: introduce get_tree_bdev_flags()
As Allison reported [1], currently get_tree_bdev() will store
"Can't lookup blockdev" error message. Although it makes sense for
pure bdev-based fses, this message may mislead users who try to use
EROFS file-backed mounts since get_tree_nodev() is used as a fallback
then.
Add get_tree_bdev_flags() to specify extensible flags [2] and
GET_TREE_BDEV_QUIET_LOOKUP to silence "Can't lookup blockdev" message
since it's misleading to EROFS file-backed mounts now.
