tc: fix batch force option

Browse Source 
When sending accumulated compound command results an error, check 'force'
option before exiting. Move return code check after putting batch bufs and
freeing iovs to prevent memory leak. Break from loop, instead of returning
error code to allow cleanup at the end of batch function. Don't reset ret
code on each iteration.
