_XkbMakeAtom: remove check for impossible case
nd->string is always the result of a new allocation, so can
never be equal to string.
This resolves a warning from the gcc 12 analyzer, which reported
a memory leak if the impossible condition was ever true:
In file included from xkbatom.c:85:
xkbatom.c: In function ‘_XkbMakeAtom’:
XKBfileInt.h:51:33: warning: leak of ‘<unknown>’ [CWE-401]
[-Wanalyzer-malloc-leak]
[...]

| | ~~ ~
| | | |
| | | (17) following ‘false’ branch...
| | (16) ...to here
| 161 | _XkbFree(nd);
