Bin Meng 58303fc0be hw/riscv: Don't add empty bootargs to device tree
Commit 7c28f4da20 ("RISC-V: Don't add NULL bootargs to device-tree")
tried to avoid adding *NULL* bootargs to device tree, but unfortunately
the changes were entirely useless, due to MachineState::kernel_cmdline
can't be NULL at all as the default value is given as an empty string.
(see hw/core/machine.c::machine_initfn()).

Note the wording of *NULL* bootargs is wrong. It can't be NULL otherwise
a segfault had already been observed by dereferencing the NULL pointer.
It should be worded as *empty" bootargs.

Fixes: 7c28f4da20 ("RISC-V: Don't add NULL bootargs to device-tree")
