Subject: IB/ocrdma: Removed GID add/del null routines
Patch-mainline: v4.17-rc1
Git-commit: 115b68aa6ea4bb7dca1cbf66cb99cefc274180cb
References: bsc#1103992 FATE#326009

add_gid() and del_gid() are optional callback routines.
ib_core ignores invoking them while updating GID table entries if
they are not implemented by provider drivers. Therefore remove them.
