Gilles Peskine 2493401af4 Document that psa_close_key(0) and psa_destroy_key(0) succeed
Document that passing 0 to a close/destroy function does nothing and
returns PSA_SUCCESS.

Although this was not written explicitly, the specification strongly
suggested that this would return PSA_ERROR_INVALID_HANDLE. While
returning INVALID_HANDLE makes sense, it was awkward for a very common
programming style where applications can store 0 in a handle variable
to indicate that the handle has been closed or has never been open:
applications had to either check if (handle != 0) before calling
psa_close_key(handle) or psa_destroy_key(handle), or ignore errors
from the close/destroy function. Now applications following this style
can just call psa_close_key(handle) or psa_destroy_key(handle).
