ecore: Fix Asan stack overflow warning

Summary:
As argument can be passed by register (depending on the compiler optimization)
when we take the adress of the nbytes and pass it to send() function which reades
4 bytes from it ASAN flags it as a stack overflow . So just assign the value to a
local variable to avoid the warning.
