[PATCH] fix sysrq handling bug in sn_console.c

Fix a stupid bug in the sysrq handling in sn_console.c.  Instead of eating
all characters in the sysrq string (preventing them from getting to the tty
layer), only eat those following 'ESC' since that's a pretty important
character for various things.  Please apply before 2.6.9 is released as the
console is very unfriendly to use without it.
