staging/rdma/hfi1: Use parallel workqueue for SDMA engines
The workqueue is currently single threaded per port which for a small number of
SDMA engines is ok.
For hfi1, the there are up to 16 SDMA engines that can be fed descriptors in
parallel.
Use alloc_workqueue with a workqueue limit of the number of sdma engines and
with WQ_CPU_INTENSIVE and WQ_HIGHPRI specified.
Then change send to use the new scheduler which no longer needs to get the
s_lock
