    gdb/riscv: use register name enum values in riscv-linux-nat.c
    
    There were a few places where we were using integer values rather than
    the RISCV_*_REGNUM constants defined in riscv-tdep.h.  This commit
    replaces 0 with RISCV_ZERO_REGNUM and 32 with RISCV_PC_REGNUM in a few
    places.
    
    There should be no user visible changes after this commit.
