alpha: Fix build around srm_sysrq_reboot_op

The patch introducing the struct was probably never compile tested,
because it sets a handler with a wrong function signature. Wrap the
handler into a functions with the correct signature to fix the build.

Fixes: 0f1c9688a194 ("tty/sysrq: alpha: export and use __sysrq_get_key_op()")
