Chunhai Guo 936aa701d8 erofs: avoid useless loops in z_erofs_pcluster_readmore() when reading beyond EOF 
z_erofs_pcluster_readmore() may take a long time to loop when the page
offset is large enough, which is unnecessary should be prevented.

For example, when the following case is encountered, it will loop 4691368
times, taking about 27 seconds:
    - offset = 19217289215
    - inode_size = 1442672
