[lvc-project] [PATCH 6.1] wifi: iwlwifi: assume known PNVM power table size

[Dmitry Antipov]

In 'iwl_pnvm_load()', assume that the power table size is always
equal to IWL_HARDCODED_REDUCE_POWER_SIZE. Compile tested only.

I would gently ask Johannes to review this before taking any other
actions. This is intended for stable linux-6.1.y only in attempt to
avoid possible use of an uninitialized 'len' without backporting
