[PATCH] cris: fix a build error in drivers/tty/serial/crisv10.c

[WANG Cong]

This patch fixes the following build error:

drivers/tty/serial/crisv10.c:4453: error: 'if_ser0' undeclared (first use in this function): 2 errors in 2 logs
        v3.1-rc4/cris/cris-allmodconfig v3.1-rc4/cris/cris-allyesconfig
drivers/tty/serial/crisv10.c:4453: error: (Each undeclared identifier is reported only once: 2 errors in 2 logs
        v3.1-rc4/cris/cris-allmodconfig v3.1-rc4/cris/cris-allyesconfig
drivers/tty/serial/crisv10.c:4453: error: for each function it appears in.): 2 errors in 2 logs
        v3.1-rc4/cris/cris-allmodconfig v3.1-rc4/cris/cris-allyesconfig

"if_ser0" is a typo, it should be "if_serial_0".
