Revert "btrfs: reject unknown mount options early"
This reverts commit 5f521494cc73520ffac18ede0758883b9aedd018.
The patch breaks mounts with security mount options like
$ mount -o context=system_u:object_r:root_t:s0 /dev/sdX /mn
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdX, missing codepage or helper program, ...
We cannot reject all unknown options in btrfs_parse_subvol_options() as
intended, the security options can be present at this point and it's not
possible to enumerate them in a future proof way. This means unknown
mount options are silently accepted like before when the filesystem is
mounted with either -o subvol=/path or as followup mounts of the same
device.
