    riscv: fix errors in some atomic type aliases
    
    This appears to be a copy-and-paste error that has simply been
    overlooked. The tree contains only two calls to any of the affected
    variants, but recent additions to the test suite started exercising the
    call to atomic_clear_rel_int() in ng_leave_write(), reliably causing
    panics.
    
    Apparently, the issue was inherited from the arm64 atomic header. That
    instance was addressed in c90baf6817a0, but the fix did not make its way
    to RISC-V.
    
    Note that the particular test case ng_macfilter_test:main still appears
    to fail on this platform, but this change reduces the panic to a
    timeout.
