ath10k: fix monitor vdev for receiving other bss frames
In order to receive other BSS entries in mesh mode, Monitor vdev
is created whenever filter flag is set with OTHER_BSS. Recently
it is root caused that setting promisc filter for Mesh interface
is causing performance and stability issues. To fix this issue,
firmware will configure appropriate rxfilters by default for mesh
vdev during vdev creation. This change fixes monitor vdev creation
based on firmware IE
