[media] media-entity.c: get rid of var length arrays
Fix those sparse warnings: drivers/media/media-entity.c:238:17: warning: Variable length array is used. drivers/media/media-entity.c:239:17: warning: Variable length array is used. That allows sparse and other code check tools to verify if the function is using more stack than allowed. It also solves a bad Kernel pratice of using var length arrays at the stack.
