Subject: [PATCH][next] i3c: master: svc: remove redundant assignment to cmd->read_len

From: Colin Ian King <colin.king@...onical.com>

The assignment of xfer_len to cmd->read_len appears to be redundant
as the next statement re-assigns the value 0 to it.  Clean up the
code by removing the redundant first assignment.

Addresses-Coverity: ("Unused value")
Fixes: dd3c52846d59 ("i3c: master: svc: Add Silvaco I3C master driver")
