[ Upstream commit 063fb5bd1a01937094f40169a20e4aa5ca030db1 ]
While adding a new gid, the driver currently does not return the context back to the stack. A subsequent del_gid() (e.g, when ip address is changed) doesn't find the right context in the driver and it ends up dropping that request. This results in the HW caching a stale gid entry and traffic fails because of that. Fix by returning the proper context in bnxt_re_add_gid().
