printk: Modify operators of printed_len and text_len

Browse source

With commit <ddb9baa822> ("printk: report lost messages in printk
safe/nmi contexts") and commit <8b1742c9c2> ("printk: remove zap_locks()
function"), it seems we can remove initialization, "=0", of text_len and
directly assign result of log_output to printed_len.
