gdbserver/tracepoint.c: make exported IPA global int instead of enum

Fixes another C++ -fpermissive error:

  src/gdb/gdbserver/tracepoint.c:4535:21: error: invalid conversion from ‘int’ to ‘eval_result_type’ [-fpermissive]
    expr_eval_result = ipa_expr_eval_result;

gdb/gdbserver/ChangeLog:
2015-08-06  Pedro Alves  <palves@redhat.com>

	* tracepoint.c (expr_eval_result): Now an int.
