nci_close_device() sends nci reset command to the device.
If there is no response for this command, nci request timeout
occurs first and then cmd timeout happens. Because command
timer has started after sending the command.

We are immediately flushing command workqueue after nci
timeout. Later we will try to schedule cmd_work in command
timer which leads to a crash.

Cancel cmd_timer before flushing the workqueue to fix the
problem.

Some ACR122 firmwares seem to send 0 length data frames. Before using
that length as a data index, we check that it's not 0. If it is we
report the frame as being invalid.

SE discovery errors are currently overwriting the dev_up() return error.
This is wrong for many reasons:

- We don't want to report an error if we actually brought the device up
  but it failed to discover SEs. By doing so we pretend we don't have an
  NFC functional device even we do. The only thing we could not do was
  checking for SEs availability. This is the false negative case.

- In some cases the actual device power up failed but the SE discovery
  succeeded. Userspace then believes the device is up while it's not.
  This is the false positive case.

Some of the EEPROM configurations that are assigned by the PN544 driver
are set by the firmware and should not be modified by the driver. Others
are certain user mode configurations that are currently getting set to values
that shouldn't necessarily be dictated by the driver. This patch changes
most user and system mode configurations to the firmware defaults.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
