PATCH: pws-21: uninitialized variables

[Wayne Davison <wayne@clari.net>]

It looks like the complaint about a variable in add_match_data()
being potentially used uninitialized is valid, so this patch sets
qisl to 0.

The complaints about 4 variables in sep_comp_string() being
potentially used uninitialized appear to be bogus, but I like to get
rid of warnings, so I added initializations for them as well.
