FileAccess: Don't err in store_buffer with buffer of size 0
The error check was added for `FileAccessUnix` but it's not an error when both
`p_src` and `p_length` are zero.

Added correct error checks to all implementations to prevent the actual
erroneous case: `p_src` is nullptr but `p_length > 0` (risk of null pointer
indexing).

Fixes #33564.
