[PATCH 01/11] netdev: Fix obtaining reason code from deauth frames

[Denis Kenzior <denkenz@gmail.com>]

The reason code from deauthentication frame was being obtained as a
uint8_t instead of a uint16_t.  The value was only ever used in an
informational statement.  Since the value was in little endian, only the
first 8 bits of the reason code were obtained.  Fix that.

Fixes: 2bebb4bdc7ee ("netdev: Handle deauth frames prior to association")
