RDMA/irdma: Fix irdma_alloc_ucontext_resp padding
[ Upstream commit d95e99a74eaf35c070f5939295331e5d7857c723 ]
A recent commit modified struct irdma_alloc_ucontext_resp by adding a
member with implicit padding in front of it, though this does not change
the offset of the data members other than m68k. Reported by
scripts/check-uapi.sh:
==== ABI differences detected in include/rdma/irdma-abi.h from 1dd7bde2e91c -> HEAD ====
[C] 'struct irdma_alloc_ucontext_resp' changed:
type size changed from 704 to 640 (in bits)
1 data member deletion:
'__u8 rsvd3[2]', at offset 640 (in bits) at irdma-abi.h:61:1
1 data member insertion:
'__u8 revd3[2]', at offset 592 (in bits) at irdma-abi.h:60:1
Change the size back to the previous version, and remove the implicit
padding by making it explicit and matching what x86-64 would do by placing
max_hw_srq_quanta member into a naturally aligned location.
