This is a short series of coverity fixes for irdma.

Shiraz Saleem (2):
  RDMA/irdma: Check contents of user-space irdma_mem_reg_req object
  RDMA/irdma: Fix potential overflow expression in irdma_prm_get_pbles

v1->v2
* Add u32 sums for u16 variables to show that the operations are overflow safe.
* Replace shifting ops with DIV_ROUND_UP_ULL macro to get bits_needed
