x86/cpu/amd: Remove unnecessary parentheses 

Clang warns when multiple pairs of parentheses are used for a single
conditional statement.

arch/x86/kernel/cpu/amd.c:925:14: warning: equality comparison with
extraneous parentheses [-Wparentheses-equality]
        if ((c->x86 == 6)) {
             ~~~~~~~^~~~
arch/x86/kernel/cpu/amd.c:925:14: note: remove extraneous parentheses
around the comparison to silence this warning
        if ((c->x86 == 6)) {
            ~       ^   ~
arch/x86/kernel/cpu/amd.c:925:14: note: use '=' to turn this equality
comparison into an assignment
        if ((c->x86 == 6)) {
                    ^~
                    =
