KVM: guest_memfd: Remove redundant kvm_gmem_getattr implementation

Remove the redundant kvm_gmem_getattr() implementation that simply calls
generic_fillattr() without any special handling. The VFS layer
(vfs_getattr_nosec()) will call generic_fillattr() by default when no
custom getattr operation is provided in the inode_operations structure.

This is a cleanup with no functional change.
