Revert "PM: sleep: Do not assume that "mem" is always present"
Revert commit bfcc1e67ff1e ("PM: sleep: Do not assume that "mem" is
always present"), because it breaks compatibility with user space
utilities assuming that "mem" will always be present in
/sys/power/state.
Fixes: bfcc1e67ff1e ("PM: sleep: Do not assume that "mem" is always present")
