net/bnx2x: fix call to link handling periodic function

Browse Source 
If link handling periodic function is allowed to be called in interrupt
context, the periodic function can get called too frequently and exhaust
the retry credits to check link status.

This change makes sure link handling periodic function is not called in
interrupt context.
