[obvious] Remove unused argument in insert_bp_location

[Thiago Jung Bauermann <bauerman at br dot ibm dot com>]

Hi,

I noticed that disabled_breakpoints is not used. It's both an input and
output parameter. All callers set it to zero, and none of them checks
its value on return.

Committed the following (there were no regressions on i386-linux).

	argument.  Update callers.
