    iwlwifi: fix the gcc build
    
    - Only apply the previously added CWARNFLAGS to `drv.c` instead of the
      whole module.
    - Only apply `-Wno-initializer-overrides` to CWARNFLAGS in the clang
      scenario as it's not supported with gcc.
    
    This fixes building the module with gcc and avoids accidentally
    introducing tech debt with the module, in the event other issues are
    accidentally introduced.
    
    MFC after:      3 days
    Fixes:          6b627f8858 ("iwlwifi: update Intel's mvm/mld drivers")
    Differential Revision:  https://reviews.freebsd.org/D53591
    
    (cherry picked from commit 2ec6a2e5f01120ea8d4e667e7773d8b140e40c75)
