media: coda: cast an operand of multiplication to a larger type

Browse source

If the width and height are 0xffff (or close), the result of a
multiplication will overflow.
Cast to a larger type to avoid undefined behavior.

Such values are possible in CODA7, but unlikely.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
