RDMA: Use ib_is_udata_in_empty() for places calling ib_is_udata_cleared()

Browse source 
Convert the pattern:

  if (udata->inlen && !ib_is_udata_cleared(udata, 0, udata->inlen))

Using Coccinelle:

virtual patch
virtual context
virtual report

expression udata;

(
- udata->inlen && !ib_is_udata_cleared(udata, 0, udata->inlen)
+ !ib_is_udata_in_empty(udata)

- udata->inlen > 0 && !ib_is_udata_cleared(udata, 0, udata->inlen)
+ !ib_is_udata_in_empty(udata)

- udata && udata->inlen && !ib_is_udata_cleared(udata, 0, udata->inlen)

These cases are already checking for zeroed data that the kernel does
not understand.

Run another pass with AI to propagate the return code correctly and
remove redundant prints.
