btrfs-progs: Remove fprintf() in find_mount_root().

find_mount_root() function in utils.c should not print error string.
Caller should be responsible to print error string.

This patch will remove the only fprintf in find_mount_root() and modify
the caller a little to use strerror() to prompt users.
