common/cnxk: add workaround for vWQE flush

Due to an errata writing to vWQE flush register might hang NIX.
Add workaround for vWQE flush hang by waiting for the max
coalescing timeout to flush out any pending vWQEs.

Fixes: ee48f711f3b0 ("common/cnxk: support NIX inline inbound and outbound setup")
