[PATCH][resend] Fix potential NULL pointer deref in gen_init_cpio

[Jesper Juhl]

(This patch was already send before on Mar 18, this is a resend)

Fix potential NULL pointer deref in gen_init_cpio.c spotted by
coverity checker.
This fixes coverity bug #86

Without this patch we risk dereferencing a NULL `type' in the 
"if ('\n' == *type) {" line.
