fs: allow BtrfsIoctlLogicalInoArgs to be reused, remove virtual methods

Browse Source 
Some malloc implementations will try to mmap() and munmap() large buffers
every time they are used, causing a severe loss of performance.

Nothing ever overrode the virtual methods, and there was no virtual
destructor, so they cause compiler warnings at build time when used with
a template that tries to delete pointers to them.
