genksyms: Fix segfault with invalid declarations
commit d920f7c6628c63a390009c237fb80a203c2e400a upstream.
Do not try to recover too early and segfault when parsing invalid
declarations such as
echo 'int (int);' | scripts/genksyms/genksyms
echo 'int a, (int);' | scripts/genksyms/genksyms
echo 'extern void *__inline_memcpy((void *), (const void *), (__kernel_size_t));' | scripts/genksyms/genksyms
The last one was a real-life bug with
include/asm-generic/asm-prototypes.h on x86_64.
