Subject: [PATCH] staging: vt6656: Remove unnecesssary NULL check

pFifoHead points to tx_buffer->fifo_head which can never be NULL.
We also don't need to check for tx_buffer being NULL instead, since it
always points to ->Data of struct vnt_usb_send_context - the pointer to
which was checked before calling s_vGenerateTxParameter().

Silences a dereference before NULL check warning reported by the coverity
scanner in CID 1127221.
