[patch] rpcrt4_conn_np_read needs to expect and accept ERROR_MORE_DATA

[Luke Kenneth Casson Leighton]

this is the first and most immediate of the uses of ReadFile on
message-mode named pipes which needs attention. when ReadFile begins
to [correctly] return ERROR_MORE_DATA on short reads,
rpcrt4_conn_np_read() erroneously fails.  this causes wine to
immediately bomb out on the very first MSRPC interaction, which
happens to be a svcctl operation on wine start-up.

there are _going_ to be more of these, and a thorough audit should be
carried out of all uses of message-mode named pipes in wine to ensure
that the status code ERROR_MORE_DATA is accepted.
