Ensure in validate_label() that struct disklabel pointer is 8-byte aligned
The label is searched each 4 bytes and can be detected in an unaligned location. Before any operations on it, copy it to promptly aligned local copy on the stack. This is a missing part of the following change: revision 1.108 date: 2011-01-18 20:52:24 +0100; author: matt; state: Exp; lines: +2 -1; Make struct disklabel 8 byte aligned. This increases its size by 4 bytes on IPL32 platforms so add code in sys_ioctl (and netbsd32_ioctl) to deal with the older/smaller diskabel size. This change makes disklabel the same for both IPL32 and LP64 platforms OK by <martin>
