[PATCH][next] mm/execmem: Remove logically deadcode in execmem.c

[Everest K.C.]

NULL check of variable `area` within the `mas_for_each` loop is
unnecessary, as the varialbe `area` can never be NULL. So, the
`continue` statement inside the if block is never reached.

Remove the if block that performs the NULL check.
