Jonathan Marek a572eb5078 rpmsg: glink: use only lower 16-bits of param2 for CMD_OPEN name length
[ Upstream commit 06c59d97f6 ]

The name len field of the CMD_OPEN packet is only 16-bits and the upper
16-bits of "param2" are a different "prio" field, which can be nonzero in
certain situations, and CMD_OPEN packets can be unexpectedly dropped
because of this.

Fix this by masking out the upper 16 bits of param2.
