webgl: Re-check FBO status on binding an FBO.

Browse source 
When the FBO has been unbound, anything that happened to its
attachments (deletion, new binding, reallocation) may have caused it
to change status.

This doesn't change any test results currently, because we're not
checking if the attachments are deleted, the wrong size, or have
appropriate formats.
