Su Hui 870a2dbc7b fs: lockd: avoid possible wrong NULL parameter ...

[ Upstream commit de8d38cf44bac43e83bad28357ba84784c412752 ]

clang's static analysis warning: fs/lockd/mon.c: line 293, column 2:
Null pointer passed as 2nd argument to memory copy function.

Assuming 'hostname' is NULL and calling 'nsm_create_handle()', this will
pass NULL as 2nd argument to memory copy function 'memcpy()'. So return
NULL if 'hostname' is invalid.

Fixes: 77a3ef33e2de ("NSM: More clean up of nsm_get_handle()")
