[PATCH v2 -next] MIPS: Netlogic: Fix build error

[Guenter Roeck <linux@roeck-us.net>]

The variable 'ret' is no longer used in nlm_dma_alloc_coherent()
and causes the following build error.

arch/mips/netlogic/common/nlm-dma.c: In function 'nlm_dma_alloc_coherent':
arch/mips/netlogic/common/nlm-dma.c:50:8: error: unused variable 'ret'

Fixes: e4d0d18739dc ("dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}")

Previous version was based on next-20150824 and got it all wrong.
It might make sense to merge this into Andrew's tree, or even into
the offending patch.
