arm64: Correct wrong label in macro __init_el2_gicv3
commit 4f6de676d94ee8ddfc2e7e7cd935fc7cb2feff3a upstream.
In commit:
114945d84a30a5fe ("arm64: Fix labels in el2_setup macros")
We renamed a label from '1' to '.Lskip_gicv3_\@', but failed to update
a branch to it, which now targets a later label also called '1'.
The branch is taken rarely, when GICv3 is present but SRE is disabled
at EL3, causing a boot-time crash.
Update the caller to the new label name.
Fixes: 114945d84a30 ("arm64: Fix labels in el2_setup macros")
