In v2, move the declaration of the "p" helper variable next to the top
of the function.
Thanks!

New subject: [libnbd PATCH v2 1/2] generator/C: print_wrapper: use helper variable for permitted state check
Use a local boolean flag for unnesting the *_in_permitted_state() function
call.

Do the same as commit 0744f748ed90 ("generator: indent C argument list 2
spaces relative to function designator", 2023-04-21), except this time not
for the header files, but for "lib/api.c".
The most impactful resultant change is [lib/api.c]:
