[SERIAL] remove unneeded code from serial_core.c
This patch fixes an issue reported by Coverity in serial/serial_core.c
Error reported: Variable "&((info)->tty)->flags" tracked as NULL was passed to a
function that dereferences it.
The later statements in the function assumes 'info->tty != NULL', so this
check is not necessary. Probably a 'BUG_ON(info->tty == NULL)' can be added.
