Michael J. Ruhl b697d7d8c7 IB/hfi1: Fix incorrect mixing of ERR_PTR and NULL return values 
The __get_txreq() function can return a pointer, ERR_PTR(-EBUSY), or NULL.
All of the relevant call sites look for IS_ERR, so the NULL return would
lead to a NULL pointer exception.

Do not use the ERR_PTR mechanism for this function.

Update all call sites to handle the return value correctly.

Clean up error paths to reflect return value.

Fixes: 45842abbb2 ("staging/rdma/hfi1: move txreq header code")
