[debian-jessie-small] Fix kernel parameter parsing.

The init script uses the shell feature 'set --' to change positional
parameters for the following 'for' loop. It then mistakenly tried using
$1 to represent the requested parameter when comparing it to parsed
parameters.

Fix this by saving the requested parameter before modifying the
positional parameters.
