Btrfs-progs: make smatch checker happy (trivial fixes)

Browse Source 
It complains errno never gets assigned to zero in find-root and since
errno anyway is zero at program started up, lets remove it.

Check "copy is less then zero" isn't possible because strtoull used by
arg_strtou64 wouldn't return -ve number.

Trivial space fixes.
