Currently when the call cpr_read_fuse_uV returns an error the value in the
uninitialized variable ret is returned. Fix this by instread returning the
error value in the variable uV.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: bf6910abf548 ("power: avs: Add support for CPR (Core Power Reduction)")
