[PATCH] staging: rtl8192u: fix incorrect mask for EEPROMTxPowerLevelCCK setting

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Currently the lower 8 bits of ret are being masked and left
shifted by 8 bits always leaving a result of zero. The mask
appears to be incorrect and should probably be 0xff00 instead
of 0xff.  Fix this.  (Note: not tested).
