[RESEND PATCH v6 16/17] media: qcom: camss: Propagate vfe_reset error up the callstack

[Bryan O'Donoghue]

A previous patch I had removed the returns from vfe_disable() since we
didn't trap any meaningful errors. Konrad pointed out vfe_reset() could
return an error, which is true.

Trap the vfe_reset() error code and throw it up the callstack.
