    afs: Assert avc->lock is held in afs_IAS_once
    
    Commit 3be5880d (afs: Avoid panics in afs_InvalidateAllSegments) added
    an assert to check that vcache->lock is write-locked before we call
    afs_InvalidateAllSegments_once from a background operation.
    
    However, afs_InvalidateAllSegments_once should always be called with
    vcache->lock write-locked; there's nothing specific about the
    backgrounded call that requires this. So to make sure we catch all
    cases, move this assert to afs_InvalidateAllSegments_once itself.
    
    Also remove the conditional check for WriteLocked(&avc->lock) in here,
    since clearly avc->lock must be write-locked (and actually is, since
    change Ic309e4006bf47bcb38fa2b53bf103e0c645a856d "afs: write-lock
    vcache->lock in afs_InactiveVCache").
    
    Add some comments to this function while we're here, to more clearly
    indicate what locks are needed.
