stable inclusion
from stable-5.10.24
commit e033d7f79995daf7c2348128fbcf5084d7122d5d
bugzilla: 51348

--------------------------------

commit 6801854b upstream.

Fix usbip_sockfd_store() to validate the passed in file descriptor is
a stream socket. If the file descriptor passed was a SOCK_DGRAM socket,
sock_recvmsg() can't detect end of stream.
