Yoshinori Matsunobu 824e646341 Adding another NewFlashcacheAwareEnv function to support pre-opened fd
Summary:
There are some cases when flachcache file descriptor was
already allocated (i.e. fb-MySQL). Then NewFlashcacheAwareEnv returns an
error at open() because fd was already assigned. This diff adds another
function to instantiate FlashcacheAwareEnv, with pre-allocated fd cachedev_fd.

Test Plan: Tested with MyRocks using this function, then worked
