[LTP] [PATCH] proc01: exclude /proc/nfsd/clients/*/ctl

[Alexey Kodanev]

"ctl" files are write-only, added in Linux 5.3 with this commit
89c905beccbb ("nfsd: allow forced expiration of NFSv4 clients")

Before the patch:
proc01      1  TFAIL  :  proc01.c:396: read failed: /proc/fs/nfsd/clients/13/ctl: errno=EINVAL(22): Invalid argument
proc01      0  TINFO  :  /proc/fs/nfsd/unlock_filesystem: known issue: errno=EINVAL(22): Invalid argument
proc01      0  TINFO  :  /proc/fs/nfsd/unlock_ip: known issue: errno=EINVAL(22): Invalid argument
...

After:
proc01      0  TINFO  :  /proc/fs/nfsd/clients/13/ctl: known issue: errno=EINVAL(22): Invalid argument
proc01      0  TINFO  :  /proc/fs/nfsd/unlock_filesystem: known issue: errno=EINVAL(22): Invalid argument
proc01      0  TINFO  :  /proc/fs/nfsd/unlock_ip: known issue: errno=EINVAL(22): Invalid argument
