i386: Fix *aes<aeswideklvariant>u8

grep '{[^|}]*}"' *.md

found another spot, though dunno if we have sufficient effective targets
etc. to add an -masm=intel test for it (and my installed binutils doesn't
support it anyway).
Binutils trunk testsuite shows the argument isn't omitted even in the Intel
syntax:
grep aesencwide *.s
keylocker.s:    aesencwide128kl 126(%edx)
keylocker.s:    aesencwide256kl 126(%edx)
keylocker.s:    aesencwide128kl [edx+126]
keylocker.s:    aesencwide256kl [edx+126]
property-10.s:   aesencwide128kl (%eax)
x86-64-keylocker.s:     aesencwide128kl 126(%rdx)
x86-64-keylocker.s:     aesencwide256kl 126(%rdx)
x86-64-keylocker.s:     aesencwide128kl [rdx+126]
x86-64-keylocker.s:     aesencwide256kl [rdx+126]
and doesn't use any WHATEVER PTR.
