Fix the two following documentation build errors which were introduced
when drivers/gpu/drm/drm_gpusvm.c was refactored but when updating the
corresponding documentation, the variable and function names were not
also updated as well.

WARNING: ./drivers/gpu/drm/drm_gpusvm.c:1229 function parameter 'svm_pages' not described in 'drm_gpusvm_pages_valid_unlocked'
WARNING: ./drivers/gpu/drm/drm_gpusvm.c:1229 expecting prototype for drm_gpusvm_range_pages_valid_unlocked(). Prototype was for drm_gpusvm_pages_valid_unlocked() instead
