afs: Fix error propagation from server record check/update
afs_check/update_server_record() should be setting fc->error rather than
fc->ac.error as they're called from within the cursor iteration function.
afs_fs_cursor::error is where the error code of the attempt to call the
operation on multiple servers is integrated and is the final result,
whereas afs_addr_cursor::error is used to hold the error from individual
iterations of the call loop. (Note there's also an afs_vl_cursor which
also wraps afs_addr_cursor for accessing VL servers rather than file
servers).
Fix this by setting fc->error in the afs_check/update_server_record() so
that any error incurred whilst talking to the VL server correctly
propagates to the final result.
This results in:
kAFS: Unexpected error from FS.StoreData -512
being seen, even though the store-data op is non-interruptible. The error
is actually coming from the server record update getting interrupted.
