In MSI-X mode, if there are interrupts already notified but not cleared

To fix this issue, replace e1000e_update_interrupt_state() with
two new functions: e1000e_raise_interrupts() and
e1000e_lower_interrupts(). These functions don't only raise or lower
interrupts, but it also performs register writes which updates the
interrupt state. Before it performs a register write, these function
determines the interrupts already raised, and compares with the
interrupts raised after the register write to determine the interrupts
to notify.
The introduction of these functions made tracepoints which assumes that
the caller of e1000e_update_interrupt_state() performs register writes
obsolete. These tracepoints are now removed, and alternative ones are
added to the new functions.

igb: Always copy ethernet header
igb_receive_internal() used to check the iov length to determine
copy the iovs to a contiguous buffer, but the check is flawed in two
ways:
- It does not ensure that iovcnt > 0.
- It does not take virtio-net header into consideration.
The size of this copy is just 22 octets, which can be even less than
the code size required for checks. This (wrong) optimization is probably
not worth so just remove it. Removing this also allows igb to assume

Copying the "total counter" registers to the "good counter" registers has

If the "total" register is never read by the OS, it only gets incremented.
This leads to exponential growth of the "good" register.
