Fix : GRUB_BTRFS_LIMIT (Limit the number of snapshots populated in the GRUB menu.)
Fix : When a value =< 0, script stop correctly
Fix : When a value => 1, script stop when the value is reached
e.g :
- GRUB_BTRFS_LIMIT="0"
script doesn't detect snapshot - GRUB_BTRFS_LIMIT"1" or "2" "etc..."
script will stop the snapshot detection when value is reached
