RDMA/uverbs: Don't overwrite NULL pointer with ZERO_SIZE_PTR

Browse source

Number of specs is provided by user and in valid case can be equal to zero.
Such argument causes to call to kcalloc() with zero-length request and in
return the ZERO_SIZE_PTR is assigned. This pointer is different from NULL
and makes various if (..) checks to success.
