[PATCH 05/21] rt2x00: Move filling of TX URB to rt2x00usb_kick_tx_entry function.

[Ivo van Doorn <ivdoorn@gmail.com>]

From: Gertjan van Wingerde <gwingerde@gmail.com>

There is no need to fill the TX URB this early, and moving it to the
rt2x00usb_kick_tx_entry function allows us to merge the PCI and USB
variants of the write_tx_data function.
