From: Jianglei Nie <niejianglei2021@xxxxxxx> [ Upstream commit aa2a1df3a2c85f855af7d54466ac10bd48645d63 ] setup_base_ctxt() allocates a memory chunk for uctxt->groups with hfi1_alloc_ctxt_rcv_groups(). When init_user_ctxt() fails, uctxt->groups is not released, which will lead to a memory leak. We should release the uctxt->groups with hfi1_free_ctxt_rcv_groups() when init_user_ctxt() fails.
