    rtw89: Remove an unneeded __DECONST
    
    Originally in e2340276fc73 the function argument was a
    "const void *data" which we changed to "const int" in FreeBSD.  The
    Linux version simply cast the const void * to (enum rtw89_rf_path)
    both losing the const and changing the type.  When later the function
    argument became a const union rtw89_fw_element_arg in 5b760eaecd6c3 it
    seems we tried to undo the older FreeBSD specific part and initially
    mismerged it leading to the const void *; but when fixing the type we
    did not undo the __DECONST but did a mechanical copy.
