RDMA/hns: Modify function return value type

mainline inclusion
from mainline-v5.12-rc1
commit a33958ca
category: bugfix
bugzilla: 174002
CVE:NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a33958ca5204f8d2342fd8fe9f547e33fa6c07ed

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

hns_roce_init_qp_table() will only return 0, because this function does
not need to return a value, so it is modified to void type.
