 posix: Only check shm_unlink obj_err if necessary

 In the nominal case checked by spsysinit01, obj_err is unmodified if
 _POSIX_Shm_Get_by_name returns non-NULL. In the case of shm_unlink, this
 means
 an uninitialized value is passed into the switch and it appears tests
 using it
 were passing by virtue of the stack having the right value on it in most
 cases.
 This now checks obj_err only if _POSIX_Shm_Get_by_name returns NULL.

 Close #4016
