eliminated local variable "to_read"

The variable "to_read" is never modified except in the last iteration of the while loop. This means the while condition will never become false, as the body will break before that may be checked. git-svn-id: https://svn.musicpd.org/mpd/trunk@7396 09075e82-0dd4-0310-85a5-a0d7c8717e4f
