[tarantool-patches] [PATCH] fiber: Drop redundant memset call

[Cyrill Gorcunov <gorcunov@gmail.com>]

When we allocate new fiber we are clearing the whole
structure right after, so no need to call memset again,
coro context is already full of zeros.

Note the coro context is close to 1K size and redundat
memset here is really a penalty.
