By using a few temporary variables, smatch can track
what's happening and stops complaining that we access
beyond the tid_data array.
This also makes the generated code a bit smaller, so
it's a win all around.

Given a small change to igb_init_interrupt_scheme() the function fits
igb_request_irq() for MSI/legacy interrupts initialization as well, instead of
duplicating most of its code there.
Also adding a missing igb_configure() to igb_request_irq() for MSI fallback
to work properly.

The X540's internal thermal sensor should not be enabled for all devices, but
only those devices which enable it in the NVM image. It is expected that
actively cooled devices will have it enabled, but passively cooled devices might
not want it enabled. This is due to passively cooled devices operating very near
the thermal threshold, sometimes within the margin of error of the thermal
sensor. Thus these devices may not be good candidates for using the thermal
sensor.
This patch uses the enabled bit in the FWSM register to check whether we should
be enabling the thermal sensor, and only sets the THERMAL_SENSOR_CAPABLE flag
for those devices which have it enabled.

Old dereference of "sta" inside the call to carl9170_tx_ampdu_queue().
A range of solutions have been discussed in [2] and
we agreed on the following: "

Putting a comment there is fine. Without the comment
it's easy for a human reader to get confused why the
check is there. So long as humans can read the code,
that's all that matters."

This is really a 3-bit field, not a single bit,
so declare a mask and shift. Also fix hwsim, it
advertises the maximum possible.
While at it reindent all the defines using tabs
instead of spaces.
