dma/contiguous: avoid warning about unused size_bytes
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: c64be2bb1c6e ("drivers: add Contiguous Memory Allocator")
