A fix and test case for Bug#8330 "mysql_stmt_execute crashes" (libmysql).
libmysql/libmysql.c:
Fix for bug#8330 "mysql_stmt_execute crashes": we need to bail out
from mysql_stmt_execute if mysql->net is occupied with a result set of
another statement. Otherwise on the next attempt to use net we get
a crash, as it's freed in case of error.
