An issue found when network interface is down and up again, FPE handshake
fails to trigger. This is due to __FPE_REMOVING bit remains being set in
stmmac_fpe_stop_wq() but not cleared in stmmac_fpe_start_wq(). This
cause FPE workqueue task, stmmac_fpe_lp_task() not able to be executed.
To fix this, add clearing __FPE_REMOVING bit in stmmac_fpe_start_wq().
Fixes: 5a5586112b92 ("net: stmmac: support FPE link partner hand-shaking procedure")
