Subject: [PATCH 15/15] cgroup: Parse infinity properly for memory protections

This fixes commit db2b8d2e2895010f3443a589c9c1f1dfb25256a6 that
rectified parsing empty values but broke parsing explicit infinity.
Intended parsing semantics will be captured in a testcase in a follow up
commit.

Ref: #16248
(cherry picked from commit 67e2baff6be8052f48dfdb2258fb68d63c95fe01)
