x86/PSR: fix cmdline option handling

Commit 0ade5e causes a bug that the psr features presented in cmdline
cannot be correctly enumerated.
1. If there is only 'psr=', then CMT is enumerated which is not right.
2. If cmdline is 'psr=cmt,cat,cdp,mba', only the last feature is enumerated.

This patch fixes the issues.
