btrfs-progs: btrfs-select-super output is confusing when it fails

Browse Source 
Trivial patch:
./btrfs-progs/btrfs-select-super -s 0 /dev/sdc
using SB copy 0, bytenr 65536
No valid Btrfs found on /dev/sdc
Open ctree failed

The line 'using..' is confusing which gives an
indication that command is successful

This patch will avoid that when command fails
