proc: fix /proc/loadavg regression
Commit 95846ecf9dac ("pid: replace pid bitmap implementation with IDR
API") changed last field of /proc/loadavg (last pid allocated) to be off
by one:
# unshare -p -f --mount-proc cat /proc/loadavg
0.00 0.00 0.00 1/60 2 <===
It should be 1 after first fork into pid namespace.
This is formally a regression but given how useless this field is I
don't think anyone is affected.
Bug was found by /proc testsuite!
