gen_init_cpio: fixed fwrite warning
On compilers with security warnings enabled by default, we get: usr/gen_init_cpio.c: In function ‘cpio_mkfile’: usr/gen_init_cpio.c:357: warning: ignoring return value of ‘fwrite’, declared with attribute warn_unused_result So check the return value and handle errors accordingly.
