[dpdk-dev] [PATCH v7 2/3] net/failsafe: fix removal scope

[Matan Azrad]

The fail-safe PMD uses a per sub-device flag called "remove" to
indicate the scope where the sub-device was removed physically and
whether its software resources should be released.

This flag is set when the fail-safe receives an RMV notification
about the physical removal of the sub-device, and should be unset when
all the sub-device resources are released.

The previous code wrongly unsets the flag in dev_configure(), instead
of when the software resources release is completed.

Change the remove flag unsetting to take action in the end of the
software resources release.
