lib-smtp: smtp-server-cmd-rset - Stop processing pipeline until RSET is complete.

A subsequent MAIL command could get reset in the middle otherwise. Before, it
only blocked input until a reply was submitted, but the transaction isn't reset
until the RSET command is complete (just before actually sending the reply)
which can cause issues when the subsequent MAIL command is already being
processed.
