[PATCH] p54usb: Fix regression when using LM87 firmware

[Larry Finger]

From: Christian Lamparter <chunkeey@xxxxxx>

Commit 2b80848e3818fb1c8ccddc105b065a86c68afa9d entitled "p54usb: support LM87
firmwares" resulted in a regression when LM87 firmware is used, as this
firmware needs an explicit termination "packet" to terminate the transmission.
If this is missing, the device stalls. This problem is reported as Bugzilla
Entry No. 12260.

The original patch was suitable for the wireless-testing.git tree. This version
is designed for 2.6.28-rc9.

John,

This patch should be sent to 2.6.28, preferably before release.
