[PATCH 1/5] interrupts: fix number of bytes read for vdev

[skoteshwar at marvell.com]

From: Satha Rao <skoteshwar at marvell.com>

Correct the number of bytes to read during vdev interrupt processing.
The driver sets this value, and the rxtx interrupt handling already
performs this correctly.

Fixes: 99998feec90 ("eal/linux: add interrupt type for vdev")
