net: stmmac: Fix unbalanced IRQ wake disable warning on single irq case

Browse source

[ Upstream commit 25d7070214 ]

Commit a23aa04042 ("net: stmmac: ethtool: Fixed calltrace caused by
unbalanced disable_irq_wake calls") introduced checks to prevent
unbalanced enable and disable IRQ wake calls. However it only
initialized the auxiliary variable on one of the paths,
stmmac_request_irq_multi_msi(), missing the other,
stmmac_request_irq_single().

Add the same initialization on stmmac_request_irq_single() to prevent
"Unbalanced IRQ <x> wake disable" warnings from being printed the first
time disable_irq_wake() is called on platforms that run on that code
path.
