prlimit: Translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY [BZ #22678]
prlimit called without a new value fails on 32-bit machines if any of the soft or hard limits are infinity. This is because prlimit does not translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY, but checks that the value returned by the prlimit64 syscall fits into a 32-bit value, like it is done for example in getrlimit. Note that on the other hand new_rlimit is correctly translated from RLIM_INFINITY to RLIM64_INFINITY before calling the syscall. This patch fixes that. Changelog: [BZ #22678] * sysdeps/unix/sysv/linux/prlimit.c (prlimit): Translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY.
