Venkateswararao Jujjuri (JV) ca41bb3e21 [net/9p] Handle Zero Copy TREAD/RERROR case in !dotl case. 
This takes care of copying out error buffers from user buffer
payloads when we are using zero copy.  This happens because the
only payload buffer the server has to respond to the request is
the user buffer given for the zero copy read.

Because we only use zerocopy when the amount of data to transfer
is greater than a certain size (currently 4K) and error strings are
limited to ERRMAX (currently 128) we don't need to worry about there
being sufficient space for the error to fit in the payload.
