Reuben Hawkins 3718a48ef4 vfs: fix readahead(2) on block devices
[ Upstream commit 7116c0af4b ]

Readahead was factored to call generic_fadvise.  That refactor added an
S_ISREG restriction which broke readahead on block devices.

In addition to S_ISREG, this change checks S_ISBLK to fix block device
readahead.  There is no change in behavior with any file type besides block
devices in this change.

Fixes: 3d8f761531 ("vfs: implement readahead(2) using POSIX_FADV_WILLNEED")
