ide: decrease size of ->pc_buf field in struct ide_atapi_pc
struct ide_atapi_pc is often allocated on the stack and size of ->pc_buf
size is 256 bytes. However since only ide_floppy_create_read_capacity_cmd()
and idetape_create_inquiry_cmd() require such size allocate buffers for
these pc-s explicitely and decrease ->pc_buf size to 64 bytes.
