perf stat: Clear sample_(type|period) for counting
Clear sample_(type|period) for counting, as it only confuses debug
output with unwanted sampling details:
Before:
$ sudo perf stat -e 'raw_syscalls:sys_enter' -vv ls
------------------------------------------------------------
perf_event_attr:
type 2
size 112
config 0x11
{ sample_period, sample_freq } 1
sample_type TIME|CPU|PERIOD|RAW
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
enable_on_exec 1
exclude_guest 1
...
After:
$ sudo perf stat -e 'raw_syscalls:sys_enter' -vv ls
------------------------------------------------------------
perf_event_attr:
type 2
size 112
config 0x11
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
enable_on_exec 1
exclude_guest 1
...
