sysfs: treewide: constify attribute callback of bin_attribute::llseek()

Browse Source 
The llseek() callbacks should not modify the struct
bin_attribute passed as argument.
Enforce this by marking the argument as const.

As there are not many callback implementers perform this change
throughout the tree at once.
