ubifs: Fix ubifsload when using ZLIB
Using ZLIB compression with UBIFS fails if last data node is not a size of
UBIFS_BLOCK_SIZE (4096 bytes).
Easiest way to test this is trying to read a file smaller than 4k:
=> ubifsload 41000000 /etc/fstab
Loading file '/etc/fstab' to addr 0x41000000 with size 704 (0x000002c0)...
UBIFS error (pid 0): read_block: bad data node (block 0, inode 2506)
UBIFS error (pid 0): do_readpage: cannot read page 0 of inode 2506, error -22
Error reading file '/etc/fstab'
/etc/fstab not found!
exit not allowed from main input shell.
=>
With this patch:
=> ubifsload 41000000 /etc/fstab
Loading file '/etc/fstab' to addr 0x41000000 with size 704 (0x000002c0)...
Done
