Daniel Thompson 425704be09 kdb: Fix handling of kallsyms_symbol_next() return value
commit c07d353380 upstream.

kallsyms_symbol_next() returns a boolean (true on success). Currently
kdb_read() tests the return value with an inequality that
unconditionally evaluates to true.

This is fixed in the obvious way and, since the conditional branch is
supposed to be unreachable, we also add a WARN_ON().
