  btio: Handle EOPNOTSUPP from accept() to prevent busy loop

When accept() returns EOPNOTSUPP on an L2CAP SEQPACKET server socket
(e.g. AVCTP browsing channel, PSM 0x1b), the error is permanent and
retrying will never succeed. Previously, only EBADFD was treated as
fatal, causing server_cb to return TRUE for EOPNOTSUPP. Since the fd
remains readable, this creates an infinite busy loop that hangs
bluetoothd.

Treat EOPNOTSUPP the same as EBADFD by returning FALSE to remove the
GLib IO watch and stop the loop.

  profile: Check if bearer is enabled on registration

btd_profile_register now verifies that the profile's bearer type is
compatible with btd_opts.mode before registering. If the required bearer
is not enabled (e.g. LE-only profile when mode is BR/EDR, or BR/EDR-only
profile when mode is LE), registration is rejected with -ENOTSUP.

  plugins: Check btd_profile_register return value

Ensure all plugin init functions check the return value of
btd_profile_register. If registration fails (e.g. bearer not enabled),
the plugin init propagates the error instead of continuing with an
unregistered profile.

  Changed paths:

  Log Message:
  -----------
  bearer: Check btd_opts.mode on btd_bearer_new

Only create the bearer interface if the corresponding transport is
enabled. Return NULL if BREDR bearer is requested in LE-only mode or
LE bearer in BREDR-only mode, so the D-Bus interface is never
registered for unsupported bearers.
