mailbox: zynqmp-ipi: Fix out-of-bounds access in mailbox cleanup loop
The cleanup loop was starting at the wrong array index, causing
out-of-bounds access.
Start the loop at the correct index for zero-indexed arrays to prevent
accessing memory beyond the allocated array bounds.
Fixes: 4981b82ba2ff ("mailbox: ZynqMP IPI mailbox controller")
