[PATCH v2 1/2] docs: admin-guide: Handle TAINT_FORCED_BIND when parsing /proc/sys/kernel/tainted

tainted-kernels.rst contains a small script to check which taint bits
are set in /proc/sys/kernel/tainted. Add one more loop iteration to also
handle the newly added TAINT_FORCED_BIND bit.

Also simplify by starting the loop at 0 and save substracting 1 for each
usage of the loop counter.

Fixes: fcbfaffee51a ("driver core: add TAINT_FORCED_BIND for when userspace manually messes with devices and drivers")

Hello,

feel free to squash this into fcbfaffee51a without author attribution if
that is considered a good idea.

Best regards
Uwe

 script, but if you need something quick you can use this shell command to check
 which bits are set::
 
-	$ for i in $(seq 20); do echo $(($i-1)) $(($(cat /proc/sys/kernel/tainted)>>($i-1)&1));done
+	$ for i in $(seq 0 20); do echo $i $(($(cat /proc/sys/kernel/tainted)>>$i&1));done
