Subject: ice: Remove useless DMA-32 fallback configuration
Patch-mainline: v5.18-rc1
Git-commit: 9c3e54a632637f27d98fb0ec0c44f7039925809d
References: jsc#PED-376
As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.
Simplify code and remove some dead code accordingly.
