libgimpbase: fix declaration after statement and reset safecheck...
... after each successful read(). I completely missed this declaration after a statement during the review of !13 even though I saw another similar issue! Also let's reset the error counter to 0 each time a successful read() happens so that we can continue reading even if a lot of EINTR were to happen, as long as we globally go forward. Only consecutive errors increment the counter. Finally add a small comment to explain why we let EINTR pass instead of breaking directly.
