Qiushi Wu e3b04e1b5b agp/intel: Fix a memory leak on module initialisation failure
[ Upstream commit b975abbd38 ]

In intel_gtt_setup_scratch_page(), pointer "page" is not released if
pci_dma_mapping_error() return an error, leading to a memory leak on
module initialisation failure.  Simply fix this issue by freeing "page"
before return.

Fixes: 0e87d2b06c ("intel-gtt: initialize our own scratch page")
