03ce2fbaf0 driver: Fix ana_cmpr negative enum comparison
The C17 standard (sec 6.7.2.2) indicates that the underlying type of an enum is
implementation defined (i.e., can be signed or unsigned). Thus, comparing
"-1 >= some_enum" where "some_enum" is always 0 or largert can return true if
the compiler uses unsigned for enums.

This commit fixes the following issues with ana_cmpr:

- Fixed incorrect comparison in ana_cmpr_del_unit() that relied on enums being
signed, thus would always return true.
- Fixed incorrect expected argument in the "ana_cmpr_unit_install_uninstall"
test. This was not picked up due to the incorrect enum comparison above.
