Richard Levitte 0d94212a04 BIO_s_mem() write: Skip early when input length is zero 
When the input length is zero, just return zero early.  Otherwise,
there's a small chance that memory allocation is engaged, fails and
returns -1, which is a bit confusing when nothing should be written.

Fixes #4782 #4827
