Jeongjun Park 0ccef97f0c jfs: fix out-of-bounds in dbNextAG() and diAlloc()
[ Upstream commit e63866a475562810500ea7f784099bfe341e761a ]

In dbNextAG() , there is no check for the case where bmp->db_numag is
greater or same than MAXAG due to a polluted image, which causes an
out-of-bounds. Therefore, a bounds check should be added in dbMount().

And in dbNextAG(), a check for the case where agpref is greater than
bmp->db_numag should be added, so an out-of-bounds exception should be
prevented.

Additionally, a check for the case where agno is greater or same than
MAXAG should be added in diAlloc() to prevent out-of-bounds.
