[PATCH] gen_init_cpio: allocate enough space for dname

From: Colin King
Date: Tue Mar 21 2017 - 12:47:50 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The allocation of dname is short by 1 byte, so increase the allocation
size.

Detected with CoverityScan, CID#711628 ("Out-of-bounds-access (OVERRUN)")
