[PATCH] drm/etnaviv: Use unsigned type to count the number of userspace pages

[Sui Jingfeng]

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