qed: avoid truncating work queue length

[ Upstream commit 954fd908f177604d4cce77e2a88cc50b29bad5ff ]

clang complains that the temporary string for the name passed into
alloc_workqueue() is too short for its contents:

drivers/net/ethernet/qlogic/qed/qed_main.c:1218:3: error: 'snprintf' will always be truncated; specified size is 16, but format string expands to at least 18 [-Werror,-Wformat-truncation]

There is no need for a temporary buffer, and the actual name of a workqueue
is 32 bytes (WQ_NAME_LEN), so just use the interface as intended to avoid
the truncation.
