Subject: [PATCH 5.15 193/262] mips: setup: fix setnocoherentio() boolean setting

From: Randy Dunlap <rdunlap@...radead.org>

commit 1e6ae0e46e32749b130f1823da30cea9aa2a59a0 upstream.

Correct a typo/pasto: setnocoherentio() should set
dma_default_coherent to false, not true.

Fixes: 14ac09a65e19 ("MIPS: refactor the runtime coherent vs noncoherent DMA indicators")
