MIPS: Octeon: Avoid empty-body warning

gcc-6 reports a harmless build warning:

arch/mips/cavium-octeon/dma-octeon.c: In function 'octeon_dma_alloc_coherent':
arch/mips/cavium-octeon/dma-octeon.c:179:3: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]

We can fix this by rearranging the code slightly using the
IS_ENABLED() macro.
