target/cortex_m: remove target halted check when removing a breakpoint 

Remove the target halted check from cortex_m_remove_breakpoint()
as there is no such check in cortex_m_set_breakpoint() and bp can be
safely removed from the running target.

While on it return the error code from cortex_m_unset_breakpoint()
to higher level.
