While performing static tool analysis using coverity found following reports for resouse leak

bluez-5.64/plugins/sixaxis.c:425: alloc_arg: "get_pairing_type_for_device" allocates memory that is stored into "sysfs_path".
bluez-5.64/plugins/sixaxis.c:428: leaked_storage: Variable "sysfs_path" going out of scope leaks the storage it points to.

Fixing them.
