mtd: jedec_probe: initialise make sector erase command variable
In the commit 08968041bef437ec363623cd3218c2b083537ada
(mtd: cfi_cmdset_0002: make sector erase command variable)
introdused a field sector_erase_cmd. In the same commit initialisation
of cfi->sector_erase_cmd made in cfi_chip_setup()
(file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem:
...
cfi->cfi_mode = CFI_MODE_CFI;
cfi->sector_erase_cmd = CMD(0x30);
...
But for the JEDEC chips this initialisation is not carried out,
so the JEDEC chips have sector_erase_cmd == 0.
This patch adds the missing initialisation.
