[PATCH] drm/amd/display: Fix logical operator in get_meta_and_pte_attr()

[Srinivasan Shanmugam]

logical operator in a condition check in the get_meta_and_pte_attr
function bitwise AND operator '&' was used in an 'if' statement, but the
logical AND operator '&&' was likely intended.

The condition check was changed from:
    if (!surf_linear & (log2_dpte_req_height_ptes == 0) & surf_vert)
to the below:
    if (!surf_linear && (log2_dpte_req_height_ptes == 0) && surf_vert)

This ensures that the 'if' statement will be true only if all three
conditions are met, which is the typical use case in an 'if' statement.

Fixes the below:
