media: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update()
vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop
bound and passes the index to vfe_isr_reg_update(). However,
vfe->line[] array is defined with VFE_LINE_NUM_MAX(4):
struct vfe_line line[VFE_LINE_NUM_MAX];
When index is 4, 5, 6, the access to vfe->line[line_id] exceeds
the array bounds and resulting in out-of-bounds memory access.
Fix this by using separate loops for output lines and write masters.
