perf/core: Fix address filter parser for multiple filters
[ Upstream commit d680ff24e9e14444c63945b43a37ede7cd6958f9 ]
Reset appropriate variables in the parser loop between parsing separate
filters, so that they do not interfere with parsing the next filter.
Fixes: 375637bc524952 ("perf/core: Introduce address range filtering")
