net: libwx: fix VMDQ mask for 1-queue mode

In wx_set_vmdq_queues(), the VMDQ mask was not set for the devices not
supporting WX_FLAG_MULTI_64_FUNC, i.e., NGBE devices. A mask of 0 causes
__ALIGN_MASK(1, ~vmdq->mask) to return 0, which incorrectly sets
q_per_pool to 0 in wx_write_qde().

Fix the VMDQ 1-queue mask to 0x7F then ensures that __ALIGN_MASK(1,
~0x7F) correctly evaluates to 1.
