IB/hfi1: Handle kzalloc failure in init_pervl_scs
Checking the return value of the memory allocation call in
init_pervl_scs() was missed. Recently the kmalloc() was changed to
kzalloc() which identified the problem.
While fixing this issue 2 other bugs were noticed. First, the array
being allocated is accessed in the nomem path which can be reached before
it is allocated. Second, kernel_send_context was not released on error.
Fix both of these by creating a more common memory unwind label structure.
Fixes: 35f6befc8441 ("staging/rdma/hfi1: Add qp to send context mapping for PIO")
