Subject: Windows: AFSRemoveCcb cannot fail
X-Git-Tag: upstream/1.8.0_pre1^2~1638
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=207890788079c82d81a1a7f2a0972ed165583798;p=packages%2Fo%2Fopenafs.git

Windows: AFSRemoveCcb cannot fail

Since AFSRemoveCcb cannot fail, change the signature from returning
NTSTATUS to void.

Remove all error handling code.
