    RISC-V: Fix one unused varable in riscv_subset_list::parse
    
    This patch would like to fix one unused variable as below:
    
    ../../gcc/common/config/riscv/riscv-common.cc: In static member function
    'static riscv_subset_list* riscv_subset_list::parse(const char*, 
location_t)':
    ../../gcc/common/config/riscv/riscv-common.cc:1501:19: error: unused 
variable 'itr'
      [-Werror=unused-variable]
     1501 |   riscv_subset_t *itr;
    
    The variable consume code was removed but missed the var itself in
    previous.  Thus, we have unused variable here.
    
    gcc/ChangeLog:
    
            * common/config/riscv/riscv-common.cc (riscv_subset_list::parse):
            Remove unused var decl.
