[Drbd-dev] [PATCH] DRBD 8.0 return error when vmalloc fail

[Stanislaw Gruszka]

Bitmap allocation failure is not visible for users. First reason is drbradm
not return status of executed commands  Second determin_dev_size() function
return enum value which badly become non negative at function output from
negative error code (at least for gcc3) . Attached patch is fix for these issues.
