As you have already been informed by other helpful members, it's really not a problem - just be sure to use rolling x-strokes when honing the opposite side so as to avoid any uneven wear there if necessary (it will likely be hitting heavier in the middle on that side). Use regular x-strokes for the warped side.

I wouldn't go crazy removing steel when you don't have to. This will flatten out your spine but it may also make the bevel wonky (technical term).
if the blade makes perfect contact on the oter side and honeware is even...then the spine is straight but it is overground in the middle on the side with limited spine contact.

if the blade has problems on both sides...then the blade is warped
