[PATCH 08/14] PMFS: Fix endian warnings in pmfs_inode_crawl_recursive()

[Matthew Wilcox]

From: Matthew Wilcox <willy at linux.intel.com>

Fix the type of 'btype' to be the u8 it actually is on media, and compare
it against the native PMFS_BLOCK_TYPE_* value, instead of byteswapping it
(which would be silly since it's a single byte).  This probably fixes
a bug on big-endian machines.
