[PATCH blktests 1/3] tests/block/030: Make this test less noisy

Since test block/030 injects blk_mq_realloc_hw_ctxs() failures, it is
expected that writes into the 'submit_queues' attribute can fail. Send
the 'nproc: write error: Cannot allocate memory' failures to $FULL instead
of stderr. See also commit a668c61064f2 ("Add a test that triggers the
blk_mq_realloc_hw_ctxs() error path").
