Should an error occur (invalid TLV len or memory allocation failure), the
memory already allocated in 'reduce_power_data' should be freed before
returning, otherwise it is leaking.

The variable 'package_size' is an unsigned long, and should be printed
out using '%lu', not '%zd' (that would be for a size_t).
Yes, on many architectures (including x86-64), 'size_t' is in fact the
same type as 'long', but that's a fairly random architecture definition,
and on some platforms 'size_t' is in fact 'int' rather than 'long'.
That is the case on traditional 32-bit x86. Yes, both types are the
exact same 32-bit size, and it would all print out perfectly correctly,
but '%zd' ends up still being wrong.
And we can't make 'package_size' be a 'size_t', because we get the
actual value using efivar_entry_get() that takes a pointer to an
'unsigned long'. So '%lu' it is.
This fixes two of the i386 allmodconfig build warnings (that is now an
error due to -Werror).

This new feature allows OEMs to set a special reduced power table in a
UEFI variable, which we use to tell the firmware to change the TX
power tables.
Read the variable and store it in a dram block to pass it to the
firmware. We do this as part of the PNVM loading flow.
