USB: serial: metro-usb: fix up coding style errors 

This fixes up all of the coding style errors, and removes the initial,
unneeded comments on how to load the module and the old changelog which
are no longer needed.

There are still a number of coding style warnings left, I'll get to them
later.

File Name: metro-usb.c
Description: metro-usb.c is the drivers main source file. The driver is a USB to Serial converter.
The driver takes USB data and sends it to a virtual ttyUSB# serial port.
The driver interfaces with the usbserial.ko driver supplied by Linux.
NOTES:
To install the driver:
1. Install the usbserial.ko module supplied by Linux with: # insmod usbserial.ko
2. Install the metro-usb.ko module with: # insmod metro-usb.ko
Some of this code is credited to Linux USB open source files that are distributed with Linux.

1/30/2007 Philip Nicastro Initial release. (v1.0.0.0)
2/27/2007 Philip Nicastro Changed the metrousb_read_int_callback function to use a loop with the tty_insert_flip_char function to copy each byte to the tty layer. Removed the tty_buffer_request_room and the tty_insert_flip_string function calls. These calls were not supported on Fedora.
2/27/2007 Philip Nicastro Released. (v1.1.0.0)
10/07/2011 Aleksey Babahin Update for new kernel (tested on 2.6.38)
Add unidirection mode support
