[PATCH for_v23 v2 5/9] x86/sgx: WARN only once if EREMOVE fails

[Sean Christopherson <sean.j.christopherson@xxxxxxxxx>]

WARN only once if EREMOVE fails to avoid spamming the kernel log if a
catastrophic failure occurs.  Warning on every failure is helpful for
development, but is a bad idea for production code as EREMOVE rarely
fails just once...
