rpmsg: char: Add mutex protection for rpmsg_eptdev_open()
There is no mutex protection for rpmsg_eptdev_open(),
especially for eptdev->ept read and write operation.
It may cause issues when multiple instances call
rpmsg_eptdev_open() in parallel,the return state
may be success or EBUSY.
Fixes: 964e8bedd5a1 ("rpmsg: char: Return an error if device already open")
