Phillip Lougher 1f13dff09f squashfs: don't call kmalloc in decompressors 
The decompressors may be called while in an atomic section.  So move the
kmalloc() out of this path, and into the "page actor" init function.

This fixes a regression introduced by commit
f268eedddf ("squashfs: extend "page actor" to handle missing pages")
