Fixed CID 1269712, 1269709, 1269706, 1269703, 1269694: Logically dead code
Remove extra NULL check as OMPI_OSC_PT2PT_REQUEST_ALLOC can never set the
request to NULL.
Fixes CID 1269668: Unchecked return value
False positive. Add (void) to indicate we do not care about the return code
from opal_hash_table_get_uint32.
Fixes CID 1324726: Free of address-of expression
Do not free lock if it was not allocated.
Fixes CID 1269658: Free of address-of expression
Never will happen but because op is always a built-in op there is no
reason to retain/release it anyway.
