[PATCH -next] MIPS: OCTEON: fix error - use 'ret' after remove it

[Qinglang Miao]

Variable ret was removed in commit 0ee69c589ec("MIPS: OCTEON:
use devm_platform_ioremap_resource") but still being used in
devm_release_mem_region which is unneeded. So remove this
line to fix error.

Fixes: 0ee69c589ec("MIPS: OCTEON: use devm_platform_ioremap_resource")
