perf trace: Set errpid to false for rseq and set_robust_list
The 'rseq' and 'set_robust_list' syscalls don't return a pid, so set
errpid for both to false.
Fixes: 0c1019e3463b263a ("perf trace: Mark the 'rseq' arg in the rseq syscall as coming from user space")
Fixes: 1de5b5dcb8353f36 ("perf trace: Mark the 'head' arg in the set_robust_list syscall as coming from user space")

[ Remove explicit .errpid = false, omitting its initialization zeroes it, as noted by Namhyung ]
