assuan_read_from_server() and return value

[Ben Kibbey]

I'm using assuan_transact() to process an inquire command. After the
command is finished, assuan_transact() sends "END" then reads the next
line from the server via assuan_read_from_server().
assuan_read_from_server() will parse an ERR line, but won't do anything
with the error code. Attached is a patch that'll return the server error
code. Doesn't seem to break anything.
