perf: Revert duplicated commit

This reverts commit 92341529
'perf: Fix parsing of __print_flags() in TP_printk()'.  The same
change was already included in 3.2 as commit
d06c27b2 but in 3.2.1 this change
was wrongly applied to similar code in a different function.

Thanks to Jiri for pointing this out in 3.0.y.
