NFSv4/pnfs: Fix a use-after-free bug in open

either the open slot or the layoutget operation arguments, since they
are likely still in use by the hung RPC call.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
