rtlwifi: rtl8192cu: Remove unused parameter

rtl_ps_set_rf_state's protect_or_not parameter is not set to
true anywhere, except for commented out code.

It enables some legacy locking code, which is no longer used,
so delete the parameter and the old locking code.

iwlagn: don't check ucode subtype

The ucode subtypes keep changing, and there's no
particular reason to be checking them (other than
a paranoid sanity check). Since the numbers are
also in conflict between different ucode images
now, simply don't check them any more and rely on
the images being built correctly.

Also, to indicate that, rename the constants and
the enum, moving it to a different file.

At http://dev.laptop.org/ticket/10748 we are seeing a case of the
libertas firmware randomly stopping responding to commands after

hardware bug, which has been reported to Marvell.

Work around this issue by adding a reset_card method; this is

instant recovery to this situation.
