Is it really needed to sleep after the MMIO write access?

Having used zmalloc, the memset looks overkill. Also, it does not clear
all the allocated are, don't know if this is expected.

sw_rings_phys should be renamed to sw_rings_iova, as it could be a VA if
IOVA_AS_VA more is used.

Same comment regarding phys vs. iova in this function.
