char: esp.c: fix possible double-unlock

Hitting either of the break statements in the while loop would cause a
double-unlock of info->lock.

[Jiri Slaby suggested simply returning is safe here, rather than a goto]

Noticed by sparse:
drivers/char/esp.c:2042:2: warning: context imbalance in 'rs_wait_until_sent' - unexpected unlock
