IB/hfi1: Fix expected receive setup error exit issues
Fix three error exit issues in expected receive setup.
Re-arrange error exits to increase readability.
Issues and fixes:
1. Possible missed page unpin if tidlist copyout fails and
not all pinned pages where made part of a TID.
Fix: Unpin the unused pages.
2. Return success with unset return values tidcnt and length
when no pages were pinned.
Fix: Return -ENOSPC if no pages were pinned.
3. Return success with unset return values tidcnt and length when
no rcvarray entries available.
Fix: Return -ENOSPC if no rcvarray entries are available.
Fixes: 7e7a436ecb6e ("staging/hfi1: Add TID entry program function body")
Fixes: 97736f36dbeb ("IB/hfi1: Validate page aligned for a given virtual addres")
Fixes: f404ca4c7ea8 ("IB/hfi1: Refactor hfi_user_exp_rcv_setup() IOCTL")
