Input: sysrq - drop tty argument form handle_sysrq()

Sysrq operations do not accept tty argument anymore so no need to pass

[Stephen Rothwell <sfr@canb.auug.org.au>: fix build breakage in drm code
 caused by sysrq using bool but not including linux/types.h]

[Sachin Sant <sachinp@in.ibm.com>: fix build breakage in s390 keyboadr
 driver]
