mtd: spi-nor: improve wait-till-ready timeout loop
There are a few small issues with the timeout loop in
spi_nor_wait_till_ready():
* The first operation should not be a reschedule; we should check the
status register at least once to see if we're complete!
* We should check the status register one last time after declaring the
deadline has passed, to prevent a premature timeout error (this is
theoretically possible if we sleep for a long time after the previous
status register check).
* Add an error message, so it's obvious if we ever hit a timeout.
