posix: Fix fgetxattr() crash when key name is NULL

This is used to get the size of xattr list (to later allocate buffer):
glfs_flistxattr(glfd, NULL, 0);

glfs_flistxattr() internally has the following call:
syncop_fgetxattr (subvol, fd, &xattr, NULL, NULL, NULL);

strncmp() segfaults as name is NULL in posix_fgetxattr()

Turns out this was a coverity fix in master branch that was not
backported to 3.7.x tree.
