84fa994f51 rpmsgdev: rpmsgdegv ioctl and seek buf fix
1. rpmsgdev ioctl: should assgin back the client return value to
   cookie->result, then this return value can be returned to the
   application;
2. rpmsgdev seek: the type "off_t" may be 64bit, so modify the offset
   in "struct rpmsgdev_lseek" to int64_t too;
3. rpmsgdev_seek: the rpmsgdev_seek in client should update the
   filep->f_pos after the seek operation;

c860a6e5f1 rpmsgdev: forward all open/close to server to support complex driver
Before this commit, each rpmsgdev server only manages one file
no matter how many times the client opened.
It can't work fine with some complex drivers, such as input driver
(keyboard, touchscreen and button), because input driver will alloc
a new private open structure for every open operation to make sure
all the applications don't miss data when input driver is used by
multiple applications.
This commit solves this problem by making the files in server and
client be one-to-one.
