fs: rename inode member of struct filep to priv ...

Because that's what it is. 'inode' will become confusing
once we support real inodes.

The struct device_d * in struct filep is never of interest, instead

|     ext4fs: le32_to_cpu() used on a 16-bit field
|
|     Fix reading ext4_extent_header struture on BE machines.  Some 16 bit
|     fields where converted to 32 bit fields, due to the byte swap on BE
|     machines the containing value was corrupted. Therefore reading ext4
|     filesystems on BE machines where broken before.

fs: ext4: fix "invalid extent block" error ...

From U-Boot commit:

| commit b5bbac1
| Author: Ionut Nicu <ioan.nicu.ext@nsn.com>
| Date:   Mon Jan 13 12:00:08 2014 +0100
|
|     ext4fs: fix "invalid extent block" error
|
|     For files where we actually have extent indexes following
|     an extent header (ext_block->eh_depth != 0), the do/while
|     loop from ext4fs_get_extent_block() does not select the
|     proper extent index structure.
|
|     For example, if we have:
|
|     ext_block->eh_depth = 1
|     ext_block->eh_entries = 1
|     fileblock = 0
|     index[0].ei_block = 0
|
|     the do/while loop will exit with i set to 0 and the
|     ext4fs_get_extent_block() function will return 0, even if
|     there was a valid extent index structure following the
|     header.

automount: check for recursive automount ...

automount_mount calls run_command which may trigger an automount
again. This results in an endless loop. A simple way to trigger
this is:

mkdir /x; automount /x false; cd /x; something

Use a static variable to detect if we are currently in automount_mount()
and bail out if we are.
