[PATCH 2/5] trace-cmd: Don't call exit from tracecmd_blk_hack()

[Vaibhav Nagarnaik]

Commit 9e0fd22b14805a3a3219a99bc5eccebf70f5484a adds a hack to parse
blktrace events. In tracecmd_blk_hack(), if the block trace events could
not be parsed, it calls exit(0). Get rid of it and only return -1 to let
the caller know that parsing failed.
