net: e1000: annotate switch/case fallthrough

Browse Source 
The E1000 driver uses an implicit switch/case fallthrough for sharing
some code supporting different PHYs.

Add our "fallthrough;" statement-like macro before the two labels in
e1000_set_phy_type(), to avoid a warning when GCC's -Wimplicit-fallthrough
warning option is enabled.
