btrfs: fix information leak in btrfsioctllogicaltoino()

Syzbot reported the following information leak for in btrfsioctllogicaltoino():

Bytes 40-65535 of 65536 are uninitialized Memory access of size 65536 starts at ffff888045a40000

This happens, because we're copying a 'struct btrfsdatacontainer' back to user-space. This btrfsdatacontainer is allocated in 'initdatacontainer()' via kvmalloc(), which does not zero-fill the memory.

Fix this by using kvzalloc() which zeroes out the memory on allocation.
