We don't actually need to return an output parameter providing mm sequence number, rather we can separate that out into another function - __vma_raw_mm_seqnum() - and have any callers which need to obtain that invoke that instead. The access to the raw sequence number requires that we hold the exclusive mmap lock such that we know we can't race vma_end_write_all(), so move the assert to __vma_raw_mm_seqnum() to make this requirement clear. Also while we're here, convert all of the VM_BUG_ON_VMA()'s to VM_WARN_ON_ONCE_VMA()'s in line with the convention that we do not invoke oopses when we can avoid it.
