i40e: return false from i40e_reset_vf if reset is in progress
[ Upstream commit a2c90d63b71223d69a813333c1abf4fdacddbbe5 ]
The function i40e_vc_reset_vf attempts, up to 20 times, to handle a
VF reset request, using the return value of i40e_reset_vf as an indicator
of whether the reset was successfully triggered. Currently, i40e_reset_vf
always returns true, which causes new reset requests to be ignored if a
different VF reset is already in progress.
This patch updates the return value of i40e_reset_vf to reflect when
another VF reset is in progress, allowing the caller to properly use
the retry mechanism.
Fixes: 52424f974bc5 ("i40e: Fix VF hang when reset is triggered on another VF")
