commit 7e27cb2352b4f48935e85e3288a24ac03c3d1f83

features/uss: Perform NULL check on @name in svc_getxattr
LISTXATTR fop is internally converted into a GETXATTR with
the "name" parameter set to NULL. In svc_getxattr(), a listxattr
was causing a crash because of a NULL pointer dereference on @name.
FIX:
Add the necessary NULL check.
