Grissiom f615c1e92d Revert "Merge pull request #241 from bright-pan/master" 
This reverts commit 5aeedc4f3a, reversing
changes made to 3d80e414ff.

This merge breaks every uart driver in all BSPs. @bright-pan , is there
any way to get this done without breaking existing code?

Grissiom 6bb2c0f2ea Revert "serial: set the errno if and only if in thread context" 
This reverts commit 07bd09fc0f.
The validation of the context is done with in `rt_set_errno`. So it's
safe to call it here.

Grissiom 07bd09fc0f serial: set the errno if and only if in thread context 
The errno is associated with threads. It will crash the thread if we set
it in interrupt context.
