[PATCH] bcachefs: use mustfix to check invalid btree IDs

[Bharadwaj Raju]

Checking for invalid IDs was introduced in 9e7cfb35e266 ("bcachefs: Check for invalid btree IDs")
to prevent an invalid shift later, but since 141526548052 ("bcachefs: Bad btree roots are now autofix")
made the parent class btree_root_bkey_invalid FSCK_AUTOFIX, fsck_err_on
no longer works for this check.

Change the condition to use mustfix_fsck_err_on instead.

Fixes: 141526548052 ("bcachefs: Bad btree roots are now autofix")
