MAINTAINERS: adjust file entry in NVIDIA GHES HANDLER

Commit d761085 ("ACPI: APEI: GHES: Add NVIDIA vendor CPER record
handler") adds the file drivers/acpi/apei/ghes-nvidia.c and also adds a
section NVIDIA GHES VENDOR CPER RECORD HANDLER in the MAINTAINERS file with
a file entry referring to drivers/acpi/apei/nvidia-ghes.c. Note that the
file name in the entry (nvidia-ghes.c) differs from the actual file in
the repository (ghes-nvidia.c).

Adjust the file entry to the actual existing file.
