genksyms: Fix segfault with invalid declarations
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.
