RDMA/hns: Fix error with to_hr_hem_entries_count()
For ilog2(x), if x is 0 and not a constant variable, it will return
-1. And there will be an error as below:
hns3 0000:7d:00.0 hns_0: Local work queue 0x8 catast error, sub_event type is: 2
So modify to_hr_hem_entries_shift() to return 0 if conut is 0.
