Christopher Bednarz bb6d73d9ad RDMA/irdma: Prevent zero-length STAG registration 
Currently irdma allows zero-length STAGs to be programmed in HW during
the kernel mode fast register flow. Zero-length MR or STAG registration
disable HW memory length checks.

Improve gaps in bounds checking in irdma by preventing zero-length STAG or
MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set.

This addresses the disclosure CVE-2023-25775.
