dm stripe: avoid divide by zero with invalid stripe count
If a table containing zero as stripe count is passed into stripe_ctr
the code attempts to divide by zero.
This patch changes DM_TABLE_LOAD to return -EINVAL if the stripe count
is zero.
We now get the following error messages:
device-mapper: table: 253:0: striped: Invalid stripe count
device-mapper: ioctl: error adding target to table
