ext4: add mext_check_validity() to do basic check

Browse source

Currently, the basic validation checks during the move extent operation
are scattered across __ext4_ioctl() and ext4_move_extents(), which makes
the code somewhat disorganized. Introduce a new helper,
mext_check_validity(), to handle these checks. This change involves only
code relocation without any logical modifications.
