tty: sysrq: switch sysrq handlers from int to u8
The passed parameter to sysrq handlers is a key (a character). So change
the type from 'int' to 'u8'. Let it specifically be 'u8' for two
reasons:
* unsigned: unsigned values come from the upper layers (devices) and the
tty layer assumes unsigned on most places, and
* 8-bit: as that what's supposed to be one day in all the layers built
on the top of tty. (Currently, we use mostly 'unsigned char' and
somewhere still only 'char'. (But that also translates to the former
thanks to -funsigned-char.))
