sysrq: Remove duplicated sysrq message

The commit 97f5f0cd8cd0a0544 ("Input: implement SysRq as a separate input
handler") added pr_fmt() definition. It caused a duplicated message
prefix in the sysrq header messages, for example:

[ 177.053931] sysrq: SysRq : Show backtrace of all active CPUs
[ 742.864776] sysrq: SysRq : HELP : loglevel(0-9) reboot(b) crash(c)
