net: qrtr: fix usage of idr in port assignment to socket
[ Upstream commit 8dfddfb79653df7c38a9c8c4c034f242a36acee9 ]
Passing large uint32 sockaddr_qrtr.port numbers for port allocation
triggers a warning within idr_alloc() since the port number is cast
to int, and thus interpreted as a negative number. This leads to
the rejection of such valid port numbers in qrtr_port_assign() as
idr_alloc() fails.
To avoid the problem, switch to idr_alloc_u32() instead.
Fixes: bdabad3e363d ("net: Add Qualcomm IPC router")
