wifi: ath12k: fix ath12k_qmi_alloc_chunk() to handle too large allocations

Browse source

If the requested memory chunk is too large, an error message is logged, but the
request continues to be processed. However, no actual memory is allocated to
the firmware from this request. Instead, the firmware sends another request
with smaller chunks, where memory will be allocated accordingly. Therefore, it
is pointless to proceed with parsing the request if at least one of the
requests cannot be fulfilled.

Hence, return -EAGAIN immediately and proceed to process the new request.
