From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The while-loop iterates until src is non-null or i is 3, however, the
loop counter i is not intinitialied to zero, causing incorrect iteration
counts. Fix this by initializing it to zero.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 1aa5f2e2feed ("erofs: support decompress big pcluster for lz4 backend")
