Currently implemented temperature compensation is only valid on some of
supported chips. Other chips do not need temperature compensation or
need different way to do this (not yet implemented in the rt2800
driver). Trying to do run rt2800_get_gain_calibration_delta() when this
is not appropriate on particular chip gives bogus result of TX power
and can make connection unstable.
This is follow up to commit 8c8d2017ba25c510ddf093419048460db1109bc4
"rt2800: fix RT5390 & RT3290 TX power settings regression". On that
commit we avoid setting BBP_R1 register, but the real problem is wrong
temperature compensation calculation.

Proper operation with the rewritten PCI mini driver requires that a flag be set
when interrupts are enabled. This flag was missed. This patch is one of three needed to
fix the kernel regression reported at https://bugzilla.kernel.org/show_bug.cgi?id=88951.

In the major update of the rtlwifi-family of drivers, one of the callback entries
was missed, which leads to memory corruption. Unfortunately, this corruption
never caused a kernel oops, but showed up in other parts of the system.

Since the net-detect information is stored in cfg80211, and in theory
it could change while we are waking up and reading the matched
