Subject: msm: camera: don't cut to 8bits for validating enum variable
In msm_ispif_is_intf_valid(),
we convert a enum variable msm_ispif_vfe_intf,
to uint8_t type for validating.
This could cause potential issue,
if the value is crafted in such a way that lower 8bits pass the validation.
Don't use uint8_t as input parm to avoid such vulnerability.
