drivers/rptun/rptun_bmp: wait for the resource table to be initialized
The two cores of a BMP link share one resource table, and only one of
them initializes it. rptun_bmp_get_resource() returned the table right
away, so the core that does not own it could start parsing an
uninitialized table and find no vdev.
Wait in rptun_bmp_get_resource() until the table header has a non-zero
version. Both roles wait, since the table can be set up by either the
master or the slave depending on the board.
