Make a update about this issue.
  When we change rx_urb_size in the host side and keep it same as the QMAP
related QMI, this issue is "fixed".
  I also checked some old commit which related with rx_urb_size, let's say 
https://patchwork.kernel.org/project/linux-usb/patch/20200803065105.8997-1-yzc666@xxxxxxxxxxx/
and
https://patchwork.ozlabs.org/project/netdev/patch/20200909091302.20992-1-dnlplm@xxxxxxxxx/#2524381.
They tried to update the rx_urb_size to make QMAP works better. But these
commits seems have been rejected.
  So do we have any new solutions or workarounds about changing the
rx_urb_size?
