USB: musb: fix musb_host_tx() for shared endpoint FIFO
The input queue should be used for TX on endpoints which
share FIFO hardware. The host TX path wasn't doing that.
Shared FIFOs are most often configured for periodic endpoints,
which are mostly used for RX/IN transfers ... that's probably
how this bug managed to linger for a long time.
