kern linker: Do not retry loading modules on EEXIST

Description

kern linker: Do not retry loading modules on EEXIST

LINKER_LOAD_FILE() calls linker_load_dependencies() which will return
EEXIST in case the module to be loaded has already been compiled into
the kernel. Since the format of the module is now recognized then there
is no need to retry loading with a different linker, otherwise the
userland will get misleading error number ENOEXEC.
