[PATCH v3 5/5] i3c: master: adi: Fix error propagation for CCCs

[Jorge Marques]

adi_i3c_master_send_ccc_cmd() always returned 0, ignoring the transfer
result populated in the completion path. As a consequence, CCC command
errors were silently dropped, including the default -ETIMEDOUT and
later overwritten by adi_i3c_master_end_xfer_locked().

Fix this by returning xfer->ret so that callers correctly receive any
transfer error codes.
