wangjianyu3 a5b85fcd96 misc/rpmsgdev: Fix invalid pointer error when there are more than one remotes 
Test: (see tests/testcases/rpmsgdev for details)
  # 1. Register dummy device
  testdev -d 0 -r "/dev/ttyGNSS0"
  # 2. Call rpmsgdev_export() to export the device to remote
  testdev -d 2 -c "droid" -l "/dev/ttyGNSS0"
