Aborting the current read attempt on the superframe also removes the
packet from the pipeline. Retries should not be attempted on the next
packet since it would not be a superframe(either a superframe descriptor
or other data packet) and should not be handled by brcmf_sdio_rxglom

During initialization of the device, but also on some other
moments the driver prints an error that the netdev already exists.
This is a result of the way the driver is initializing the
firmware and not really an error. The code is not treating it as
an error either. This error print has resulted in many questions
by users and is confusing and incorrect. This patch changes the
error log into a debug info log.

FWIL is always mapping back errors to EBADE. This is not very
conventient when trying to understand problems by reading logs.
Some callers print the error code, but that is quite useless
when the exact error code is not returned. It also makes it
impossible to differentiate based on error code. This patch
changes the return of EBADE into the actual error code.

Broadcom devices with a single 802.11 core can work on two band
concurrently using VSDB feature, ie. Virtual Simultaneous Dual-Band.
For devices that are fitted with two 802.11 cores and RF paths the
driver should support a firmware feature called RSDB, which stands
for Real Simultaneous Dual-Band. RSDB works almost autonomously in
firmware except for AP config. When the device supports RSDB then
the interface should not be brought down when configuring it,
otherwise the link (if configured) on the other interface will be
lost.
