RDMA/hns: Remove the num_cqc_timer variable

RDMA/hns: Remove the num_cqc_timer variable

BugLink: https://bugs.launchpad.net/bugs/1981864
commit db5dfbf5b201df65c1f5332c4d9d5e7c2f42396b upstream.

The bt number of cqc_timer of HIP09 increases compared with that of HIP08.
Therefore, cqc_timer_bt_num and num_cqc_timer do not match. As a result,
the driver may fail to allocate cqc_timer. So the driver needs to uniquely
uses cqc_timer_bt_num to represent the bt number of cqc_timer.

Fixes: 0e40dc2f70cd ("RDMA/hns: Add timer allocation support for hip08")
