Description of the change

Fix bug 1420303 (binlog cache I/O error might be reported twice).

MYSQL_BIN_LOG::write_cache jumps to err with write_error set in the
case the error exit path should not call sql_print_error, presumably
because it has been called already. This has been broken with the
initial 5.6 port which made sql_print_error call unconditional. Fix by
restoring the original behavior. This is tested by
rpl.rpl_semi_sync_group_commit_deadlock testcase.
