staging: sm750fb: add missing pci_release_region on error and removal
commit 8225489ddb900656cc21573b4e1b00c9181fd777 upstream.
hw_sm750_map() calls pci_request_region() but never releases the
region on error paths or in lynxfb_pci_remove(). This causes a
resource leak that prevents the PCI region from being mapped again
after driver removal or a failed probe. A TODO comment in the code
acknowledges this missing cleanup.
Restructure the error handling in hw_sm750_map() to properly release
the PCI region on ioremap failures, and add pci_release_region() to
lynxfb_pci_remove().
