Arnd Bergmann 7ff4034e91 staging: vc04_services: shut up out-of-range warning
The comparison against SIZE_MAX produces a harmless warning on 64-bit
architectures:

drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:185:16: error: result of comparison of constant 419244183493398898 with expression of type 'unsigned int' is always false [-Werror,-Wtautological-constant-out-of-range-compare]
        if (num_pages > (SIZE_MAX - sizeof(struct pagelist) -
            ~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Shut up that warning by adding a cast to a longer type.

Fixes: ca641bae6d ("staging: vc04_services: prevent integer overflow in create_pagelist()")
