[PATCH] perf script: Fix error when printing 'weight' field

[German Gomez]

In SPE traces the 'weight' field can't be printed in perf-script because
the 'dummy:u' event doesn't have the WEIGHT attribute set.

Use evsel__do_check_stype(..) to check this field, as it's done with
other fields such as "phys_addr".

Before:

$ perf record -e arm_spe_0// -- sleep 1
$ perf script -F event,ip,weight
Samples for 'dummy:u' event do not have WEIGHT attribute set. Cannot print 'weight' field.

After:

$ perf script -F event,ip,weight
   l1d-access:               12 ffffaf629d4cb320
   tlb-access:               12 ffffaf629d4cb320
       memory:               12 ffffaf629d4cb320
