USB: serial: fix DMA buffers on stack for io_edgeport.c

The original code was passing a stack variable as a dma buffer, so I
made it an allocated variable.  Instead of adding a bunch of kfree()
calls, I changed all the error return paths to gotos.

Also I noticed that the error checking wasn't correct because
usb_get_descriptor() can return negative values.

While I was at it, I made an unrelated white space change by moving
the unicode_to_ascii() on to one line.
