SubjectRe: [GIT PULL] ucounts: Count rlimits in each user namespace

On second look that sigpending < LONG_MAX check is necessary. When
inc_rlimit_ucounts detects a problem it returns LONG_MAX.

So the check for LONG_MAX is the condensed check to see if there is a
problem in any other levels of the ucount hierarchy.
