PATCH: Always use breakpoint_enabled in breakpoint.c

[Phil Muldoon <pmuldoon@redhat.com>]

While stepping though breakpoint.c, I noticed two trivial areas of 
breakpoint checking that were not using the breakpoint_enabled function. 
Change to consistently use the breakpoint_enabled function over directly 
checking the breakpoint->enable_state.

2008-07-31  Phil Muldoon  <pmuldoon@redhat.com>

    * breakpoint.c (hw_breakpoint_used_count): Use breakpoint_enabled().
    (insert_breakpoint_locations): Likewise.
