[PATCH v2 3/5] [gdb/symtab] Simplify assignment in lnp_state_machine::record_line

[Tom de Vries <tdevries@suse.de>]

Function lnp_state_machine::record_line contains this conditional assignment:
...
  if (m_last_address != m_address)
    {
      ...
      m_last_address = m_address;
    }
...

While it's true that there's no need to update m_last_address if
m_last_address == m_address, this can be expressed much simpler using an
unconditional assignment:
...
  m_last_address = m_address;
...

Fix this by using an unconditional assignment, and moving it alongside a
similar assignment:
...
+  m_last_address = m_address;
   m_last_line = m_line;
...

Tested on x86_64-linux.
