Local variable msi_idx defined as unsigned int is always >= 0, thus both

suggests the checks should not be trivially true.
The simplest solution is to replace incorrect checks with direct testing
of adap->flags and remove spare variables.

The problem has been detected using semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci

The correct fix is to have local variable 'msi_idx' as int instead of unsigned
int. Thanks for reporting the issue. Do you want me to send a V2?

Thanks,
