properly.

For some reason a portYIELD() is not enough to give the serial task the
option to run. I tried vTaskDelay() and that works. To not block more than
needed portYIELD() is still called when the queue is not full and only
call vTaskDelay() when it is full.

The MSC interrupts can come in back to back, effectively blocking
the FreeRTOS timer task which resets the watchdog. This simple fix
simply resets the watchdog when performing an MSC read or write.

They won't get modified, so make them const.  Also reformat a bit so
they look prettier.

These two static variables aren't (and shouldn't!) be used anywhere
outside of bhi160_fetch_fifo() so let's move them into the function.

Signed-off-by: Rahix <rahix@rahix.de>

bhi160_fetch_fifo() doesn't actually return any meaningful error values
anymore.  Remove return-value checks and make the function return void
to express this clearly.

The -EIO error was triggering a warning in the caller.
