msm: ipahal: modify parameter from eq_bitfield[i] to i

From IPAv4.5 versions IPA_TOS_EQ is considered as not supported
and it made to 0XFF, instead IPA_IS_PURE_ACK is given support.
So, when validating the bitfield equations of them, passing
eq_bitfield[i] will throw shift overflow warning as it takes 0xFF.
So, added change to ensure there are no overflow warnings.
