[Qemu-trivial] [PATCH trivial 0/3] vl: simplify code for main() and get_boot_device()

[Chen Gang]

In "vl.c", at least, we can simplify the code below, so can let readers
read professional C code (especially for new readers, which often start
reading code at main function).

 - remove useless 'continue' in main().

 - remove redundant local variable 'res' in get_boot_device().

 - remove local variable 'args' in the middle of code block in main().

The following 3 patches are for the 3 'remove' above.

And "vl.c" has a very long function main() which is about 17K lines.
Next, it can be split into sub-functions (so can bypass another code
style issue: multiple "{...}" styles within "swith(...)").
