perf intel-pt: Fix parsing of VM time correlation arguments
Parser did not take ':' into account.
Example:
Before:
$ perf record -e intel_pt//u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.026 MB perf.data ]
$ perf inject -i perf.data --vm-time-correlation="dry-run 123"
$ perf inject -i perf.data --vm-time-correlation="dry-run 123:456"
Failed to parse VM Time Correlation options
0x620 [0x98]: failed to process type: 70 [Invalid argument]
$
After:
$ perf inject -i perf.data --vm-time-correlation="dry-run 123:456"
$
Fixes: e3ff42bdebcfeb5f ("perf intel-pt: Parse VM Time Correlation options and set up decoding")
