bcachefs: Fix BCH_IOCTL_FSCK_OFFLINE for encrypted filesystems

To open an encrypted filesystem, we use request_key() to get the
encryption key from the user's keyring - but request_key() needs to
happen in the context of the process that invoked the ioctl.

This easily fixed by using bch2_fs_open() in nostart mode.
