gh-143689: Fix BufferedReader.read1 leaving object in reentrant state on error (#143690 )

BufferedReader.read1() could leave the buffered object in a
reentrant (locked) state when an exception was raised while
allocating the output buffer.

This change ensures the internal buffered lock is always released
on error, keeping the object in a consistent state after failures.
