perf trace: Fix IS_ERR() vs NULL check bug

Browse source

[ Upstream commit b0f4ade163 ]

The alloc_syscall_stats() function always returns an error pointer
(ERR_PTR) on failure.

So replace NULL check with IS_ERR() check after calling
alloc_syscall_stats() function.

Fixes: fc00897c8a ("perf trace: Add --summary-mode option")
