Correct two incorrectly merged changes introduced in sysv_sem.c:1.71: return EINVAL rather than setting error, and don't free sops unconditionally.  The first change was merged accidentally as part of the larger set of changes to introduce MAC labels and access control, and potentially lead to continued processing of a request even after it was determined to be invalid.  The second change was due to changes in the semaphore code since the original work was performed.
