[PATCH v2 0/4] LE Set CIG Parameters / Create CIS fixes

This patchset fixes a few issues with emission of HCI Remove CIG, Set
CIG Parameters, Create CIS when multiple ISO sockets in the same CIG are
closed and reconnected rapidly.

v2: Dropped patches that added error checking in hci_le_set_cig_params,
    TBD separately later.  Returning errors there triggers some race
    condition in the emulator when it's cleaning up the connections, which
    needs some more looking.

    Simplified the Set CIG Parameters event parsing.

    The patches here now are enough to make the test suite pass, and
    enough to fix the race conditions encountered in BlueZ ISO ops.

Pauli Virtanen (4):
  Bluetooth: ISO: use hci_sync for setting CIG parameters
  Bluetooth: ISO: don't try to remove CIG if there are bound CIS left
  Bluetooth: ISO: use correct CIS order in Set CIG Parameters event
  Bluetooth: ISO: do not emit new LE Create CIS if previous is pending
