firmware: zynqmp: fix write to an uninitialised pointer in ipi_req()
When a caller is not interested in the returned message, the ret_payload
pointer is set to NULL in the u-boot-sources. In this case, under EL3, the
memory from address 0x0 would be overwritten by ipi_req() with the returned
IPI message, damaging the original data under this address. The patch, in
case ret_payload is NULL, assigns the pointer to the array holding the IPI
message being sent.
