    plug-ins: fix some warnings.
    
    Should have paid more attention. I left 2 warnings in the file:
    
    > plug-ins/common/file-raw-data.c:1949:22: warning: variable ‘procedure’ set but not used 
[-Wunused-but-set-variable]
    
    > plug-ins/common/file-raw-data.c:1970:48: warning: ‘bpp’ may be used uninitialized in this function 
[-Wmaybe-uninitialized]
