RDMA/hfi1: fix potential memory leak in setup_base_ctxt()

Browse Source 
[ 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.

Fixes: e87473bc1b6c ("IB/hfi1: Only set fd pointer when base context is completely initialized")
