Baokun Li c0db17e55f ext4: add two helper functions extent_logical_end() and pa_logical_end() ...

commit 43bbddc067883d94de7a43d5756a295439fbe37d upstream.

When we use lstart + len to calculate the end of free extent or prealloc
space, it may exceed the maximum value of 4294967295(0xffffffff) supported
by ext4_lblk_t and cause overflow, which may lead to various problems.

Therefore, we add two helper functions, extent_logical_end() and
pa_logical_end(), to limit the type of end to loff_t, and also convert
lstart to loff_t for calculation to avoid overflow.
