RDMA/hns: Remove the num_qpc_timer variable

mainline inclusion
from mainline-v6.0-rc5
commit 45baad7d
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7WVK1
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=45baad7dd98f4d83f67c86c28769d3184390e324

----------------------------------------------------------------------

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

Fixes: 0e40dc2f ("RDMA/hns: Add timer allocation support for hip08")
