[dpdk-dev] [PATCH v5 2/3] net/failsafe: fix removal scope

[Matan Azrad]

Fail-safe PMD uses per sub-device flag called "remove" to indicate the
scope where the sub-device isn't synchronized with the fail-safe state.

This flag is set when fail-safe gets RMV notification about the
physical removal of the sub-device and should be unset when the
sub-device completes all the configurations cause it to arrive to the
fail-safe state.

The previous code wrongly unsets the flag after calling to the
sub-device PMD dev_configure() operation and before all the
configurations were done.

Change the remove flag unsetting to be only after the sub-device
successes to arrive to the fail-safe state.

Fixes: a46f8d5 ("net/failsafe: add fail-safe PMD")
