r_mkdir: don't truncate the path on error (#322)

Browse source 
currently, in case of error, r_mkdir will leave the path at a truncated
state.

a7d39b0ab8 is the commit that introduced this change, and in it the
error printing is moved from r_mkdir to the caller, which makes me think
it was probably intentional.

make it so that the function itself prints the error/warning
message and returns the path back to the caller unharmed.
