smpp_smsc: Fix socket read() error handling

Read returning -1 is an error here so make sure to print the actual
reason and close the socket. Before this patch we just looped over the
fd with read returning -1 every time.

EINTR is handled to not cause an error and we don't need to check
EAGAIN/EWOULDBLOCK since the callback is only called in case there is
something to read.

To avoid copy&paste issues the check is implemented as a macro and the
log message moved into a separate if.
