Summary:
- Recently I noticed that the nxhello caused hard fault
- Finally, I found that mq_open() had been changed to nxmq_open()
but the calling convention was not correct.
- This commit fixes this issue.
Impact:
- nxmu_server.c only
Testing:
- Tested with nxhello, nxlines & nxdemo with the following configs
- spresense:wifi, spresense:wifi_smp
