Btrfs: return the internal error unchanged if btrfs_get_extent_fiemap() call failed for SEEK_DATA/SEEK_HOLE inquiry

Given that ENXIO only means "offset beyond EOF" for either SEEK_DATA or SEEK_HOLE inquiry
in a desired file range, so we should return the internal error unchanged if btrfs_get_extent_fiemap()
call failed, rather than ENXIO.
