In slim_do_transfer(), when a transaction needs a tid and
slim_alloc_txn_tid() fails, the function returns directly instead of
jumping to slim_xfer_err. The runtime PM vote taken earlier with
pm_runtime_get_sync() is then never released, leaving the controller
permanently powered up.
As txn->tid is still 0 at that point, jumping to slim_xfer_err drops
the vote exactly like it is done for other failed transactions.
Fixes: d3062a2109 ("slimbus: messaging: add slim_alloc/free_txn_tid()")
