[PATCH v2 3/3] iwlwifi: pcie: trans: Remove unused 'shift_param'

[PATCH v2 3/3] iwlwifi: pcie: trans: Remove unused 'shift_param'

[Kirtika Ruchandani]

shift_param is defined and set in iwl_pcie_load_cpu_sections
but not used. Fix this to avoid -Wunused-but-set-variable
warning.
The code using it turned into dead code with commit dcab8ecd5617
which added a separate function iwl_pcie_load_given_ucode_8000
(then 8000b) for IWL_DEVICE_FAMILY_8000. Commit 76f8c0e17edc
removed the dead code but left shift_param as is.

iwlwifi/pcie/trans.c: In function ‘iwl_pcie_load_cpu_sections’:
iwlwifi/pcie/trans.c:871:6: warning: variable ‘shift_param’ set but not used [-Wunused-but-set-variable]

Fixes: dcab8ecd5617 (iwlwifi: mvm: support ucode load for family_8000 B0 only)
Fixes: 76f8c0e17edc (iwlwifi: pcie: remove dead code)

I'll remove Harary's Cc here too, since this email is not valid anymore
and I don't know his new one (and he probably doesn't care anymore
anyway).
