ibmvnic: account for bufs already saved in indir_buf

This fixes a crash in replenish_rx_pool() when called from ibmvnic_poll()
after a previous call to replenish_rx_pool() encountered an error when
allocating a socket buffer.

Thanks to Rick Lindsley and Dany Madden for helping debug the crash.

Fixes: 4f0b6812e9b9 ("ibmvnic: Introduce batched RX buffer descriptor transmission")
