drm/i915/gem: Fix Virtual Memory mapping boundaries calculation

In the Linux kernel, the following vulnerability has been resolved:

drm/i915/gem: Fix Virtual Memory mapping boundaries calculation

Calculating the size of the mapped area as the lesser value
between the requested size and the actual size does not consider
the partial mapping offset. This can cause page fault access.

Fix the calculation of the starting and ending addresses, the
total size is now deduced from the difference between the end and
start addresses.

Additionally, the calculations have been rewritten in a clearer
and more understandable form.
