Get buffer size issues #201
Description
The convolve wrapper buffer size functions (pure-C, MVE, DSP variants) are missing the (input_dims->c == filter_dims->c) check present in the wrapper functions, causing buffer under-allocation when input_dims->c != filter_dims->c.
Also arm_convolve_wrapper_s4_get_buffer_size MVE path call the s8 buffer size variant instead of the s4 variant.
