firmware: arm_scmi: Fix base agent discover response
According to scmi specification, the response of the discover agent request
is made of:
- int32 status
- uint32 agent_id
- uint8 name[16]
but the current implementation doesn't take into account the agent_id field
and only allocates a rx buffer of SCMI_MAX_STR_SIZE length
Allocate the correct length for rx buffer and copy the name from the
correct offset in the response.
While no error were returned until v5.15, v5.16-rc1 fails with virtio_scmi
transport channel:
| arm-scmi firmware:scmi0: SCMI Notifications - Core Enabled.
| arm-scmi firmware:scmi0: SCMI Protocol v2.0 'Linaro:PMWG' Firmware version 0x2090000
| scmi-virtio virtio0: tx:used len 28 is larger than in buflen 24
