[libmultipath] Fix segfault, when the syfs attribute doesn't exist

open '/class/fc_transport/target7:0:0'/'node_name'
new uncached attribute '/sys/class/fc_transport/target7:0:0/node_name'
add to cache '/sys/class/fc_transport/target7:0:0/node_name'
stat '/sys/class/fc_transport/target7:0:0/node_name' failed: No such file or directory

This would allocate no space for attr->value but and the next lookup tries to
dereference a NULL pointer.
