objtool: Add bch2_trans_unlocked_error() to bcachefs noreturns

[ Upstream commit 31ad36a271290648e7c2288a03d7b933d20254d6 ]

Fix the following objtool warning during build time:

    fs/bcachefs/btree_trans_commit.o: warning: objtool: bch2_trans_commit_write_locked.isra.0() falls through to next function do_bch2_trans_commit.isra.0()
    fs/bcachefs/btree_trans_commit.o: warning: objtool: .text: unexpected end of section
......
    fs/bcachefs/btree_update.o: warning: objtool: bch2_trans_update_get_key_cache() falls through to next function flush_new_cached_update()
    fs/bcachefs/btree_update.o: warning: objtool: flush_new_cached_update() falls through to next function bch2_trans_update_by_path()

bch2_trans_unlocked_error() is an Obviously Correct (tm) panic() wrapper,
add it to the list of known noreturns.
