btrfs-progs: Fix the argument requirement for '--subvol-extents'
The following commit changed the argument requirement for
'--subvol-extents', which causes it to call arg_strtou64() on NULL,
resulting a segfault.

This patch revert the patch and change the help string and man page to
make it no longer confusing.
