[dpdk-dev] [PATCH] igb_uio: remove PCI reset during uio device open

[Shijith Thotton <shijith.thotton@caviumnetworks.com>]

Issuing reset during uio device open caused PMD init failure for some
NIC VFs (i40, ixgbe, qede) in host. So this initial reset is removed.
Bus master enable is kept as part of open since we disable it in uio
device release.

Fixes: b58eedfc7dd5 ("igb_uio: issue FLR during open and release of device file")
