    misc/raspberrypi-gpioshutdown: fix build on recent FreeBSD
    
    Due to -Werror being enabled for kernel modules these days, the build
    of this module failed with a "variable set but not used" warning.
    Remove the offending variable to fix the build.
    
    Approved by:    portmgr (build fix blanket)
    MFH:            2024Q4
    
    (cherry picked from commit ed4dd3bfc4326cd2262f5215491eab8cd172a2c2)
