perf hists: Resort after filtering hierarchy
In hierarchy mode, a filter can affect periods of entries in upper
hierarchy. So it needs to resort the hists after filter.
For example, let's look at following example:
Overhead Command / Shared Object / Symbol
------------ --------------------------------
30.00% perf
20.00% perf
10.00% main
5.00% pr_debug
5.00% memcpy
10.00% [kernel.vmlinux]
8.00% memset
2.00% cpu_idle
If we apply simbol filter for 'mem' it should look like this
13.00% perf
8.00% [kernel.vmlinux]
8.00% memset
5.00% perf
5.00% memcpy
