In rx_SlowWritePacket the use of RX_MAXWVECS was incorrect.  The
niovecs field is allocated as [RX_MAXWVECS+1] with the 0th element
reserved for the rx header.  niovecs[RX_MAXWVECS] is therefore a
valid data buffer and the comparison should be (i <= RX_MAXWVECS).

This error has most likely not been noticed previously because
nothing in the OpenAFS source tree uses this function.
