mtd: sharpslpart: Fix unsigned comparison to zero
commit f33113b542219448fa02d77ca1c6f4265bd7f130 upstream.
The unsigned variable log_num is being assigned a return value
from the call to sharpsl_nand_get_logical_num that can return
-EINVAL.
Detected using Coccinelle:
./drivers/mtd/parsers/sharpslpart.c:207:6-13: WARNING: Unsigned expression compared with zero: log_num > 0
