vgaarb: remove bogus checks
neither ->release() nor ->poll() can be called unless ->open() has succeeded on the same struct file, so checking for "has open() failed" is pointless. What's more, ->poll() doesn't return -E... - it always returns a bitmap of POLL... values, so the dead code in that one had been actively bogus. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
