[PATCH 3/4] rt2x00: Don't free register information on suspend

[Ivo van Doorn <ivdoorn@xxxxxxxxx>]

After suspend & resume the rt2x00 devices won't wakeup
anymore due to a broken register information setup.
The most important problem is the release of the EEPROM
buffer which is completely cleared and never read again
after the suspend.
