[PATCH][ocfs2-next] ocfs2: don't use a bool for error return from call to ocfs2_get_clusters

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently a bool is being used to get and check for a -ve error
return from the call to ocfs2_get_clusters but the check for ret < 0 is
never true for a bool.  Fix this by using an int type for an error return
instead.

Detected by CoverityScan, CID#1463416 ("Operands don't affect result")
