e2fsck: zero errcode when checking inline data blocks

When checking inline data blocks, always zero pctx->errcode because
otherwise a previous error condition could leak through and "cause" a
fatal block iteration failure.  I found this by corrupting an xattr
block on an inline_data inode and fsck aborted when I tried to repair
it.
