staging: ccree: remove unused and redundant variable idx

Browse Source 
Variable idx is being set but never read and thus it can be
removed because it is redundant. Cleans up clang build warnings:

warning: Value stored to 'idx' during its initialization is never read
warning: Value stored to 'idx' is never read
warning: Value stored to 'idx' is never read
