msm: mdss: modify userspace src format during MSMFB_SET on rotator

The req->src.format field should be changed to the destination
format and propagated to the user so that appropriate buffer size
calculations for the destination buffer can be made. Note, this
only changes the user copy and the driver fetches the source buffer
based on source format.

Fix uninitialized div_s64 for gcc 4.9

I know we aren't even close to using gcc 4.9, so this might not get merged
for a while, but here it is for when the time comes. :)  4.9 is even more finicky.

Missing include.
