cifs: fix offset handling in cifs_iovec_write
In the recent update of the cifs_iovec_write code to use async writes, the handling of the file position was broken. That patch added a local "offset" variable to handle the offset, and then only updated the original "*poffset" before exiting. Unfortunately, it copied off the original offset from the beginning, instead of doing so after generic_write_checks had been called. Fix this by moving the initialization of "offset" after that in the function. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
