RDMA/hns: Bugfix for qpc/cqc timer configuration 

commit 887803db86 upstream.

qpc/cqc timer entry size needs one page, but currently they are fixedly
configured to 4096, which is not appropriate in 64K page scenarios. So
they should be modified to PAGE_SIZE.

Fixes: 0e40dc2f70 ("RDMA/hns: Add timer allocation support for hip08")
