Zheng Zengkai 48bf1a9af8 perf record: Fix memory leak when using '--user-regs=?' to list registers ...

[ Upstream commit 2eb5dd418034ecea2f7031e3d33f2991a878b148 ]

When using 'perf record's option '-I' or '--user-regs=' along with
argument '?' to list available register names, memory of variable 'os'
allocated by strdup() needs to be released before __parse_regs()
returns, otherwise memory leak will occur.

Fixes: bcc84ec65a ("perf record: Add ability to name registers to record")
