part: check each variable for capability calculation
In order to calculate the capability, we use the below expression to check:
((dev_desc->lba * dev_desc->blksz)>0L)
If the capability is greater than 4GB (e.g. 8GB = 8 * 1024 * 104 * 1024),
the result will overflow, the low 32bit may be zero.
Therefore, change to check each variable to fix this potential issue.
