Qiushi Wu 7d755eab2b agp/intel: Fix a memory leak on module initialisation failure ...

[ Upstream commit b975abbd382fe442713a4c233549abb90e57c22b ]

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: 0e87d2b06cb46 ("intel-gtt: initialize our own scratch page")
