From Pete Batard: Fix unwanted 'Unsupported NM flag settings' messages
More great work from From Robert Kausch (https://savannah.gnu.org/patch/index.php?8302):

- make buffer size unlimited again in buffered mode
- do not set Spt.Cdb[4] to buffer size as position of allocation size field depends on CDB size and is not always at byte 4, rely on caller to set the field as in direct mode
- fix memory leak in case of an error in buffered mode (p_sptwb was not freed)
- use stack allocated structure in direct mode to prevent constant reallocation of memory (note that before the patch, memory was allocated to include the buffer as well, which was pointless as an already allocated buffer is passed in direct mode)
- rename direct mode unsigned int parameters u_* to match buffered mode parameter names
- fix top comment to use correct parameter names and include u_cdb
Direct mode is functionally unchanged.

lib/driver/osx.c: probe devices before querying media list

The problem with IOServiceGetMatchingServices is that the result is cached by the system so if you insert or remove a disc between two calls, you won't get updated information.

To get an up to date media list, we need to probe the storage devices using IOServiceRequestProbe before each call.
