The fw_rx_stats entry in debugfs was getting truncated because the
internal buffer used to hold the string was too short. The
calculation of the needed buffer size was rather bogus.
Simplify the calculation by multiplying the number of entries in the
entire structure by the size of each data line and adding the size of
the header lines.
Additionally, add the mac_id value, which was missing.

The firmware always expects the Coex Mode to be set.
Moreover, the firmware expects bit 0 is the valid bits to
be set all the times.
I misunderstood the API and didn't set these bits when
commands are sent to update the paramters of the Coex. As
a result, the firmware understood that the BT Coex was
disabled (Coex mode = 0) and ignored all the updates (valid
bit 0 clear).

At the firmware level, IBSS support has similar programming
requirements as AP/GO support, so use the same functions with
just small differences.
With IBSS only a single virtual interface can be used, so no
changes in the advertised interface combinations are needed.
For now, don't use hardware crypto for the GTKs in IBSS mode,
the firmware should support it though.

In commit 3d81535ea5
(rt2800: 5592: add chip specific vgc calculations)
the rt2800_link_tuner function has been modified to
adjust VGC level for the RT5592 chipset.
On the RT5592 chipset, the VGC level must be adjusted
only if rssi is greater than -65. However the current
code adjusts the VGC value by 0x10 regardless of the
actual chipset if the rssi value is between -80 and
-65.
Fix the broken behaviour by reordering the if-else
statements.
