c06fc7ce147e57ab493bad9263f1601b8298484b io_uring: fix short read slow path
sqeq.off here is the offset to read within the disk image, so obviously
not 'nread' (the amount we just read), but as the author meant to write
its current value incremented by the amount we just read.
Normally recent versions of linux will not issue short reads,
but it can happen so we should fix this.
This lead to weird image corruptions when short read happened
