Kerogit fa7f81c34e arch/avr: fix up_saveusercontext 
The up_saveusercontext function leverages USER_SAVE macro,
which is ordinarily used as a first half of the context switch.
This macro is therefore unsuitable to be used standalone,
it pops return address from the stack and does not return.

This patch adds missing instructions to do what would otherwise
be done by the second half of the context switch.

Tested by compiling and verifying the disassembly - the function
no longer falls through to the next function in the program memory,
push/pop instructions are balanced and stack contents preserved
