[PATCH V2 05/17] i3c: master: Remove stale GETSTATUS length check

[Adrian Hunter <adrian.hunter@intel.com>]

i3c_master_getstatus_locked() verifies dest.payload.len against
sizeof(*getstatus) after issuing a GETSTATUS CCC.

This check predates the introduction of dest.payload.actual_len. Since
then, dest.payload.len has held the requested transfer length and
dest.payload.actual_len has held the received length, so the check is
always false and can never detect a short response.

It also predates the addition of generic read CCC response length
validation in i3c_master_send_ccc_cmd_locked(), which now performs the
necessary check before returning success.

Remove the stale check.
