RDMA/hns: Fix cmdq parameter of querying pf timer resource

[ Upstream commit 441c88d5b3ff80108ff536c6cf80591187015403 ]

The firmware has reduced the number of descriptions of command
HNS_ROCE_OPC_QUERY_PF_TIMER_RES to 1. The driver needs to adapt, otherwise
the hardware will report error 4(CMD_NEXT_ERR).
