Subject: [PATCH 3/3] media: rzg2l-cru: Drop redundant buffer address clearing

Remove the clearing of cru->buf_addr[slot] in rzg3e_cru_irq().

The buffer address is already managed by rzg2l_cru_set_slot_addr(),
and explicitly setting it to zero here has no effect on the driver
behavior. Removing this assignment simplifies the code and avoids
unnecessary operations.
