flashrom.c, sfdp.c: Initialize dynamically allocated memory using calloc

In flashrom_image_write variables curcontents and oldcontents are
dynamically allocated using malloc. These could remain uninitialized and
when later used in need_erase could result in undefined behaviour.
Similiar reasoning for variables hbuf, hdrs, tbuf in function
prob_spi_sfdp.

So allocate them using calloc to initialize them to zeroes or if
allocating using malloc separately initialize them using a loop.
