Variables allocated by kvmalloc_array should not be freed by kfree.
Because they may be allocated by vmalloc.
So we replace kfree with kvfree here.
Fixes: 6fd610c5733d ("RDMA/hns: Support 0 hop addressing for SRQ buffer")

Variables allocated by kvzalloc should not be freed by kfree.
Because they may be allocated by vmalloc.
So we replace kfree with kvfree here.
