The CONFIG_RCU_FAST_NO_HZ stall warning messages can never emit
timer=-1. This is because the printf() format specifier to generate
that number is '%lu'. So, update the documentation to use the
unsigned long equivalent instead, timer=4294967295. This is what
actually shows up in traces.

Good catch! Even worse, it gives timer=18446744073709551615 on
64-bit systems, which is no easier on the eyes. I therefore changed
the code to print a nicer message in this case, patch below.
Looks better, thanks.
