[PATCH v2 1/2] sequencer.c: check for lock failure and bail early in fast_forward_to

Change fast_forward_to() to check if locking the ref failed, print a nice error message and bail out early. The old code did not check if ref_lock was NULL and relied on the fact that the write_ref_sha1() would safely detect this condition and set the return variable ret to indicate an error.
