powerpc/xmon: Use KSYM_NAME_LEN in array size
kallsyms_lookup() which in turn calls kallsyms_lookup_buildid() writes
to index "KSYM_NAME_LEN - 1".
Thus the array passed as namebuf to kallsyms_lookup() should be
KSYM_NAME_LEN in size.
In xmon.c the array was defined to be "128" bytes directly, without
using KSYM_NAME_LEN. Commit b8a94bfb3395 ("kallsyms: increase maximum
kernel symbol length to 512") changed the value to 512, but missed
updating the xmon code.
Fixes: b8a94bfb3395 ("kallsyms: increase maximum kernel symbol length to 512")
