Subject: [PATCH] usb: musb: do not change dev's dma_mask

Commit 8d2421e ("usb: musb: kill global and static for multi instance")
removed the global dma_mask copy and replaced by parent's DMA mask. The
problem here is that if the parent does not have a dma_mask then
musb_remove() goes kaboom.
Instead trying to fix this I was thinking we do we need to erase
dma_mask in the first place?
