fix for PiFmDma runtime error in latest 2013-02-09-wheezy-raspbian.

first fix is a type cast for which the sign was not correct
second fix is addition of a bit mask to deal with a reserved bit which now suddenly seems to be 1 (which was assumed to be 0)

All works as intended now. Commands can be written partially, and a single

write to the device file may contain multiple commands.
To achieve both of these the driver now only parses the commands on
dev_close().
