ubiformat: process command line arguments first
If libmtd_open fails, the program always exists with failure status and prints "MTD subsystem is not present". Even `ubiformat --help` produces the same result, which is definitely undesired. This patch moves command line option processing first to get the desired behavior. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
