drm/etnaviv: Use 'unsigned' type to count the number of pages

Browse Source 
The unpin_user_pages() function takes an 'unsigned long' argument to
store the number of userspace pages, and the struct drm_gem_object::size
is a size_t type. The number of pages can not be negative, hence, use
'unsigned' variable to count the number of pages.
