RDMA/hns: Bugfix for cqe hem init

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

In the current version, if using parameter cqe_entry_sz
for hns_roce_init_hem_table(), there may be thread failure
	when running connect_data_arm as below:
	thread 1 end with success
	thread 3 end with success
	thread 2 end with failure
	thread 0 end with failure

As a necessary parameter for the next process, cqe_entry_sz
should be replaced by mtt_entry_sz
