[PATCH v0 1/1] net/octeon_ep: fix mbuf data offset update

[Vamsi Krishna]

From: Vamsi Attunuru <vattun...@marvell.com>

Buffer refill routine uses mempool API instead of pktmbuf
alloc to avoid mbuf reset. Patch uses rearm to update the
mbuf fields. Also it removes redundant refill count update.

Fixes: 35dee56cee00 ("net/octeon_ep: add new fastpath routines")
