Arnd Bergmann ad03f3f852 dma/contiguous: avoid warning about unused size_bytes 
[ Upstream commit d7b98ae522 ]

When building with W=1, this variable is unused for configs with
CONFIG_CMA_SIZE_SEL_PERCENTAGE=y:

kernel/dma/contiguous.c:67:26: error: 'size_bytes' defined but not used [-Werror=unused-const-variable=]

Change this to a macro to avoid the warning.

Fixes: c64be2bb1c ("drivers: add Contiguous Memory Allocator")
