[e1000] Remove unused variable when ICR register is simply cleared
On reset and close, the ICR register is read to clear any pending
interrupts, but the value is simply ignored. Avoid assigning the
value to a variable, to inhibit a warning from gcc 4.6.
Also fix a potential race condition in reset routines which clear
interrupts before disabling them.

[igbvf] Remove some unused Linux-specific portions of igbvf.h
These unused portions trigger a compiler warning under gcc 4.6, due to
the ambiguity over the "page" field in struct igbvf_buffer.
