perf tools mem: Fix -t store option for record command
commit 33da54fa86e29b87fe1e83bd0f15b4ef2be53ecb upstream.
Michael reported 'perf mem -t store record' being broken. The reason is
latest rework of this area:
commit acbe613e0c03 ("perf tools: Add monitored events array")
We don't mark perf_mem_events store record when -t store option is
specified.
Committer notes:
Before:
# perf mem -t store record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
# perf evlist
cycles:ppp
#
After:
# perf mem -t store record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (7 samples) ]
# perf evlist
cpu/mem-stores/P
