Qianfeng Rong 4466dd3d71 dm-pcache: use int type to store negative error codes ...

Change the 'ret' variable from u32 to int to store negative error codes or
zero returned by cache_kset_close().

Storing the negative error codes in unsigned type, doesn't cause an issue
at runtime but it's ugly. Additionally, assigning negative error codes to
unsigned type may trigger a GCC warning when the -Wsign-conversion flag
is enabled.

No effect on runtime.
