btrfs: drop unused parameter options from open_ctree()

BugLink: https://bugs.launchpad.net/bugs/2102118

[ Upstream commit 87cbab86366e75dec52f787e0e0b17b2aea769ca ]

Since the new mount option parser in commit ad21f15b0f ("btrfs:
switch to the new mount API") we don't pass the options like that
anymore.
