make SysRq-T show all tasks again

show_state() (SysRq-T) developed the buggy habbit of not showing
TASK_RUNNING tasks.  This was due to the mistaken belief that state_filter
== -1 would be a pass-through filter - while in reality it did not let
TASK_RUNNING == 0 p->state values through.

Fix this by restoring the original '!state_filter means all tasks'
special-case i had in the original version.  Test-built and test-booted on
i686, SysRq-T now works as intended.
