The imagestart variable was assigned sizeof(tag) (which incorrectly
computed the pointer size rather than the struct size), but was never
actually read after the assignment in either trx_fixup() or
mtd_fixtrx(). The CRC calculations that follow use
offsetof(struct bcm_tag, header_crc) directly.
Remove the dead variable and its assignments entirely rather than fixing
the sizeof expression. No functional change.
