samhain: fix compile error on powerpc

It fails to comile samhain for powerpc(qemuppc):

| x_sh_dbIO.c: In function 'swap_short':
| x_sh_dbIO.c:229:36: error: initializer element is not constant
|   229 |       static unsigned short ooop = *iptr;
|       |                                    ^

Assign after initialization of the static variable to avoid the failure.
