powerpc/lib/sstep: Fix 'sthcx' instruction

commit a633cb1edddaa643fadc70abc88f89a408fa834a upstream.

Looks like there been a copy paste mistake when added the instruction
'stbcx' twice and one was probably meant to be 'sthcx'. Changing to
'sthcx' from 'stbcx'.

Fixes: 350779a29f11 ("powerpc: Handle most loads and stores in instruction emulation code")
