[PATCH] perf script: Fix --call-trace for Intel PT

[Adrian Hunter <adrian.hunter@intel.com>]

Make process_attr() respect -F-ip, noting also that the condition in
process_attr() (callchain_param.record_mode != CALLCHAIN_NONE) is always
true so test the sample type directly.

Example:

  Before:

    $ perf record -e intel_pt//u uname
    Linux
    [ perf record: Woken up 1 times to write data ]
    [ perf record: Captured and wrote 0.033 MB perf.data ]
    $ perf script --call-trace | head -5
           uname 30992 [006] 41758.313696574:  cbr: 42 freq: 4219 MHz (156%)                    0 [unknown] ([unknown]                                         )
           uname 30992 [006] 41758.313696907: _start                               7f71792c4100 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-2.31.so              )

           uname 30992 [006] 41758.313701574:     _dl_start                        7f71792c5128 _dl_start+0x338 (/usr/lib/x86_64-linux-gnu/ld-2.31.so              )

  After:

    $ perf script --call-trace | head -5

           uname 30992 [006] 41758.313699907: (/usr/lib/x86_64-linux-gnu/ld-2.31.so              )          _dl_start
