Fix use after free when font server connection lost

If there are multiple blocks waiting for the same font, only one of them
will have ->freeFont set. The rest will be in a state of FS_DEPENDING.

If the font server dies before the font finishes opening, the block with
->freeFont set will call ->unload_font, invalidating the pfont pointers
in the remaining FS_DEPENDING blocks.

Avoid a use after free (and potential crash) by passing conn to
fs_cleanup_font instead of dereferencing pfont to find the conn.
