[PATCH 18/18] staging/rdma/hfi1: Workaround CONFIG_SDMA_VERBOSITY timing issue

[Jubin John <jubin.john@intel.com>]

Enabling CONFIG_SDMA_VERBOSITY exposes a timing issue in the
driver/DC firmware. Removing the CCE_INT_* CSR reads from
sdma_dumpstate and a sdma_dumpstate call from the sdma_sendctrl()
works around the issue
